1 | ##Action方法和控制器环境
2 |
3 | 当请求到达时，etmvc将创建控制器对象，控制器对象会查找与“被请求的action”同名的public实例方法。如此看来，控制器的Action方法是允许被继承的。如果你希望某些方法不被作为action调用，可以将其声明为protected或者private。比如有如下的控制器：
4 |
5 | ```java
6 | public class BlogController extends ApplicationController{
7 | public String show(){
8 | return "show method";
9 | }
10 |
11 | protected String create(){
12 | return "create method";
13 | }
14 | }
15 | ```
16 |
17 | 当访问/blog/show时将输入框“show method” ，而访问/blog/create时将有“The requested resource (/test1/blog/create) is not available”的信息。
18 |
19 | Action方法允许使用控制器环境提供的一些对象：
20 |
21 | * request
22 | * response
23 | * session
24 | * servletContext
25 | * controllerPath
26 | * controllerName
27 | * actionPath
28 | * flash
29 | * exception
30 | 他们的作用应该不言自明，其中flash对象的使用方法我们将分出一个主题专门作介绍。
31 |

/Wiki/activerecord_callback.md:
--------------------------------------------------------------------------------
1 | ## ActiveRecord中的回调方法
2 |
3 | etmvc中ActiveRecord模型对象拥有很多的操作方法，其中有一类称为回调方法，在ActiveRecord模型对象的生命周期内，回调给予你更多的、更灵活控制能力。回调方法就象一个钩子，它允许在模型对象操作数据的前后执行一段逻辑，这实际就是ActiveRecord模型对象的AOP编程。
4 |
5 | ActiveRecord模型对象支持的回调方法有：
6 |
7 | |回调方法 |执行时机 |
8 | |:----|:----|
9 | |beforeCreate| 对象创建前执行 |
10 | |afterCreate |对象创建后执行 |
11 | |beforeUpdate |对象更新前执行 |
12 | |afterUpdate| 对象更新后执行 |
13 | |beforeSave |对象保存前执行 |
14 | |afterSave |对象保存后执行 |
15 | |beforeDestroy| 对象删除前执行 |
16 | |afterDestroy |对象删除后执行 |
17 |
18 | 回调方法签名：public void callbackMethodName() throws ActiveRecordException
19 |
20 | 我们举个回调方法应用的典型例子，在用户资料管理中，用户的信息除基本的信息外，还包括照片，而照片以文件的形式被保存在某个地方。为保证数据的完整性，在用户资料删除时必须同时删除其关联的照片文件。
21 |
22 | 我们来看一下用户的模型类定义：
23 |
24 | ```java
25 | @Table(name="users")
26 | public class User extends ActiveRecordBase{
27 | @Id private Integer id;
28 | @Column private String name;
29 | @Column private String phone;
30 | @Column private String filename;
31 |
32 | public void afterDestroy() throws ActiveRecordException{
33 | String path = getImagePath();
34 | File file = new File(path);
35 | if (file.exists() && file.isFile()){
36 | file.delete();
37 | }
38 | }
39 |
40 | public String getImagePath(){
41 | return "d:/temp/" + id + "_" + filename; //获取照片文件存放路径
42 | }
43 |
44 | //get,set...
45 | }
46 | ```
47 |
48 | 我们重载了afterDestroy，告诉ActiveRecord框架，在记录删除后将相关的照片文件删除。现在来看调用代码：
49 |
50 | ```java
51 | User user = User.find(User.class, 1);
52 | user.destroy();
53 | ```
54 |
55 | 我们无须在调用时编写删除照片文件的代码，仅仅将User对象删除就好，User对象会做相应的回调，执行相关的逻辑。
56 |
57 | 另外，在ActiveRecord模型对象执行回调方法时是有事务保证的，所以一旦照片文件删除失败，整个对象将执行回滚操作。如此，对于模型对象的调用者来说，这将变得更清晰。

1 | ## ActiveRecord中的数据类型映射
2 |
3 | etmvc中的ActiveRecord将数据表中的字段映射成模型类的字段，相应的将数据表中的字段类型映射成模型类的字段类型。
4 |
5 | 在多数情况下，ActiveRecord能够自动处理从JDBC类型到Java Object类型的映射，此种映射如下表所示：
6 |
7 | |JDBC 类型 | Java Object 类型 |
8 | |:-------|:----------------|
9 | |CHAR | String |
10 | |VARCHAR | String |
11 | |LONGVARCHAR | String |
12 | |NUMERIC | java.math.BigDecimal|
13 | |DECIMAL | java.math.BigDecimal|
14 | |BIT | Boolean |
15 | |TINYINT | Integer |
16 | |SMALLINT | Integer |
17 | |INTEGER | Integer |
18 | |BIGINT | Long |
19 | |REAL | Float |
20 | |FLOAT | Double |
21 | |DOUBLE | Double |
22 | |BINARY | byte[.md](.md) |
23 | |VARBINARY | byte[.md](.md) |
24 | |LONGVARBINARY | byte[.md](.md) |
25 | |DATE | java.sql.Date |
26 | |TIME | java.sql.Time |
27 | |TIMESTAMP | java.sql.Timestamp|
28 |
29 | 在类型的映射上可能存在一些需要转换的，比如在MSSQL数据库中定义了一个datetime的字段类型，而在模型类中定义了java.sql.Date类型。按照上表中的映射关系，将无法直接从datetime映射成java.sql.Date，所以需要作些转换。
30 |
31 | 我们需要为上面的这种转换编写一个转换器，转换器必须实现com.et.ar.Converter接口：
32 |
33 | ```java
34 | public class DateConverter implements Converter {
35 | @Override
36 | public Object convert(Object value) {
37 | if (value == null) {
38 | return null;
39 | }
40 | String s = value.toString().substring(0, 10); //取yyyy-mm-dd
41 | return java.sql.Date.valueOf(s);
42 | }
43 | }
44 | ```
45 |
46 | 这个转换器将对象value转换成java.sql.Date类型的对象，在上面的转换实现中，我们仅是简单地取前十个字符串，然后调用valueOf进行转换。
47 |
48 | 最后将这个转换器进行注册登记：
49 |
50 | ```java
51 | static{
52 | ConvertUtil.register(new DateConverter(), java.sql.Date.class);
53 | }
54 | ```
55 |
56 | 好了，ActiveRecord在处理到需要映射成java.sql.Date类型的字段时会调用我们自定义的转换器进行处理。
57 |

1 | ## ActiveRecord中集成spring
2 |
3 | etmvc中ActiveRecord（下称AR）在使用上可以独立使用，其数据库的连接信息通过activerecord.properties进行配置。
4 | AR提供一个简单的连接池实现，如果需要使用更高效的连接池，则可以利用spring来进行配置。AR集成spring分二步进行：
5 |
6 | 1、配置spring的连接池
7 |
8 | ```xml
9 |
10 |
11 |
12 |
13 |
14 |
15 | ```
16 |
17 | 2、配置AR的连接工厂
18 | ```xml
19 |
20 |
21 |
22 |
23 |
24 | ```
25 |
26 | 这样就完成了切换数据源的操作，下面再给出一个使用多数据库的配置实例
27 |
28 | ```xml
29 |
35 |
41 |
42 |
46 |
50 | ```

/Wiki/aroundfilter.md:
--------------------------------------------------------------------------------
1 | ## etmvc中使用环绕过滤器
2 |
3 | etmvc中支持前置过滤器，后置过滤器和环绕过滤器，前面介绍过前置过滤器了，请参阅《etmvc的过滤器基础》。
4 |
5 | 环绕过滤器是功能最强的一类过滤器，允许拦截action方法的执行前和执行后，这实际上就是一种AOP。所以通过环绕过滤器，我们可以在action方法执行前和执行后处理一些逻辑，甚至中断action的执行，可以用它做日志处理、异常处理等。
6 |
7 | etmvc中创建一个环绕过滤器同前置过滤器有些不同，前置过滤器只要简单在控制器中编写一个方法就行了，环绕过滤器必须是单独的一个类，这个类要求实现AroundHandler接口，或者继承AbstractAroundHandler。我们先来看个简单的环绕过滤器例子：
8 |
9 | ```java
10 | public class TestAroundFilter implements AroundHandler{
11 |
12 | @Override
13 | public boolean before(Controller controller) throws Exception {
14 | System.out.println("begin invoke:" + controller.getActionName());
15 | return true;
16 | }
17 |
18 | @Override
19 | public boolean after(Controller controller) throws Exception {
20 | System.out.println("after invoke:" + controller.getActionName());
21 | return true;
22 | }
23 |
24 | }
25 | ```
26 |
27 | 其中before和after分别是在action方法执行之前和之后执行，如果返回true则继续后续代码执行，如果返回false则中断后续代码执行，所以如果before返回false将中止action方法的执行。
28 |
29 | 如此，利用环绕过滤器，我们完全能够控制action方法之前和之后的逻辑，只要在before和after中编写处理逻辑的代码就行了。如若要记录日志，只要在before中记录action开始执行的时间，在after中记录action执行完成的时间，就能够清楚执行那个action，什么时间开始执行，什么时间结束执行，执行了多长时间等。
30 |
31 | 好了，我们来看看这个环绕过滤器怎样安装到控制器上，看下面的示例：
32 |
33 | ```java
34 | @AroundFilter(execute=TestAroundFilter.class)
35 | public class HelloController extends ApplicationController{
36 | public String say() throws Exception{
37 | return "hello,world";
38 | }
39 | }
40 | ```
41 |
42 | 用@AroundFilter注解就能将环绕过滤器安到控制器上，注意到这里的execute是类，而前置过滤器和后置过滤器是方法名称。如果需要安多个环绕过滤器，用@AroundFilters就好了。
43 |
44 | 在上面例子中，我们执行http://localhost:8080/xxx/hello/say时，将在TOMCAT控制台输出：
45 |
46 | begin invoke:say
47 |
48 | after invoke:say
49 |
50 |
51 |
--------------------------------------------------------------------------------
/Wiki/aroundfilter_exception.md:
--------------------------------------------------------------------------------
1 | ## etmvc中使用环绕过滤器处理异常
2 |
3 | etmvc框架中可以使用环绕过滤来处理异常，在WEB应用程序中如果需要处理全局的异常，比如我们可能需要拦截全局的异常然后集中处理，这时可以使用环绕过滤器。
4 |
5 | 下面给出一个参考的处理方法：
6 |
7 | 定义异常过滤器：
8 |
9 | ```java
10 | public class ExceptionFilter implements AroundHandler{
11 |
12 | @Override
13 | public boolean after(Controller controller) throws Exception {
14 | Exception ex = controller.getException();
15 | if (ex != null){
16 | controller.getSession().setAttribute("error", ex);
17 | controller.getResponse().sendRedirect("/myweb/application/error");
18 | return false;
19 | }
20 | return true;
21 | }
22 |
23 | @Override
24 | public boolean before(Controller controller) throws Exception {
25 | return true;
26 | }
27 |
28 | }
29 | ```
30 |
31 | 异常过滤器中检测到有异常发生，则重定向到全局的错误页面，为了方便，我们将错误页面显示的方法写在了ApplicationController类中，当然也可以专门写个处理异常的控制器：
32 |
33 | ```java
34 | @AroundFilter(execute=ExceptionFilter.class)
35 | public class ApplicationController extends Controller{
36 | public void error() throws Exception{
37 | Exception ex = (Exception)session.getAttribute("error");
38 | session.setAttribute("error", null);
39 | ex.printStackTrace();
40 | request.setAttribute("error", ex);
41 | }
42 | }
43 | ```
44 |
45 | 最后需要一个页面(/views/applicaion/error.jsp)来显示异常信息：
46 |
47 | ```jsp
48 | <%@ page language="java" contentType="text/html; charset=UTF-8"
49 | pageEncoding="UTF-8"%>
50 |
51 |
52 |
53 |
54 | Insert title here
55 |
56 |
57 | error message
58 | ${error }
59 |
60 |
61 | ```
62 |
63 | 在下面的myweb例子中执行http://localhost:8080/myweb/test/test1时成功执行，显示一个字符串，执行http://localhost:8080/myweb/test/test2时出现异常，重定向至错误页面。
64 |

/Wiki/configuration.md:
--------------------------------------------------------------------------------
1 | ## 关于etmvc的配置
2 |
3 | etmvc遵循“约定优于配置”的原则，通过文件的命名及存放位置来代替显式的配置，避免编写烦杂的XML配置文件。
4 |
5 | etmvc的配置只有一处，即在web.xml中配置一个filter，如下所示：
6 |
7 | ```xml
8 |
9 | etmvc
10 | com.et.mvc.DispatcherFilter
11 |
12 | controllerBasePackage
13 | controllers
14 |
15 |
16 | viewBasePath
17 | /views
18 |
19 |
20 | plugin
21 | plugin.OcrServer
22 |
23 |
24 |
25 | etmvc
26 | /*
27 |
28 | ```
29 |
30 | 其中，filter的初始参数有三个：controllerBasePackage, viewBasePath, plugin，说明如下：
31 |
32 | 1 controllerBasePackage是控制器的基包名称，如controllers，所有的控制器类必须在controllers包中，或者在controllers的子包中。控制器类必须以Controller结尾，必须继承Controller，比如有如下的控制器类：
33 | ```java
34 | package controllers;
35 |
36 | public class ArticleController extends ApplicationController{
37 | public View showImage(int id) throws Exception{
38 | //...
39 | }
40 |
41 | public View download(int id) throws Exception{
42 | //...
43 | }
44 |
45 | public void create(){
46 |
47 | }
48 |
49 | }
50 | ```
51 | 控制器包名是controllers，控制器类名是ArticleController，有showImage等Action方法。
52 |
53 | 2 viewBasePath是存放视图模板的位置，如下所示：
54 | 视图模板的目录结构有一定的规则，在［viewBasePath］目录下是控制器名称（小写），再往下是对应每个Action方法的视图文件。如ArticleController控制器中的方法create对应到/article/create.jsp视图文件，即执行控制器的create方法后，etmvc根据执行的结果找到对应的视图进行渲染。
55 |
56 | 3 plugin是插件的配置，一般情况下无须用到，所以不用配置该项，关于插件的使用留到后面的章节再作介绍。
57 |
--------------------------------------------------------------------------------
/Wiki/extendview.md:
--------------------------------------------------------------------------------
1 | ## 扩展etmvc的视图
2 |
3 | etmvc内置了多种常用的视图，每种视图都有对应的renderer对象，视图对象中通过加上@ViewRendererClass注解将renderer对象关联起来。比如JspView有相应的JspViewRenderer，JsonView有对应的JsonViewRenderer。
4 |
5 | 如果要使用自定义视图，则可以扩展视图，扩展视图是很简单的事情，我们需要做二件事情：一是定义视图对象，二是定义renderer对象。
6 |
7 | 假如我们要来定义一个JavaScriptView视图，用于向页面输出并执行一段JavaScript代码。首先定义视图对象，视图对象建议继承View对象：
8 |
9 | ```java
10 | @ViewRendererClass(JavaScriptViewRenderer.class)
11 | public class JavaScriptView extends View{
12 | private String js;
13 |
14 | public JavaScriptView(String js){
15 | this.js = js;
16 | }
17 |
18 | public String getJs() {
19 | return js;
20 | }
21 |
22 | public void setJs(String js) {
23 | this.js = js;
24 | }
25 | }
26 | ```
27 |
28 | 我们看到，视图对象仅是一个定义了需要的数据载体，其渲染输出是通过renderer对象完成的。下面看来一下renderer对象的定义：
29 | ```java
30 | public class JavaScriptViewRenderer extends AbstractViewRenderer{
31 | public void renderView(JavaScriptView view, ViewContext context) throws Exception{
32 | PrintWriter out = context.getResponse().getWriter();
33 | out.print("");
34 | out.close();
35 | }
36 | }
37 | ```
38 |
39 | renderer对象扩展了AbstractViewRenderer ，视图的渲染就是通过renderView方法实现的。
40 |
41 | 好了，自定义的JavaScriptView扩展完成了，我们来看看怎样使用：
42 |
43 | ```java
44 | public class TestController extends ApplicationController{
45 | public View jstest(){
46 | JavaScriptView view = new JavaScriptView("alert('abc');");
47 | return view;
48 | }
49 | }
50 | ```
51 |
52 | 我们在控制器中定义一个Action方法，只要将该方法的返回类型设为JavaScriptView就行了。
53 |

/Wiki/helloworld.md:
--------------------------------------------------------------------------------
1 | ## Hello,World经典示例
2 |
3 | 我们利用etmvc来建立一个Hello,World的WEB应用程序。
4 |
5 | 一、首先，建立新的WEB项目，引入et-mvc.jar和paranamer-1.3.jar，配置web.xml，加入一个过滤器，如下所示：
6 |
7 | ```xml
8 |
9 | etmvc
10 | com.et.mvc.DispatcherFilter
11 |
12 | controllerBasePackage
13 | controllers
14 |
15 |
16 | viewBasePath
17 | /views
18 |
19 |
20 |
21 | etmvc
22 | /*
23 |
24 | ```
25 | 我们看到，过滤器com.et.mvc.DispatcherFilter目前只有二个参数，controllerBasePackage指的是控制器的包名，viewBasePath指的是视图模板的存放目录。
26 |
27 | 二、接下来，我们开始编写控制器HelloController，一般我们会编写控制器基类ApplicationController，我们的HelloController会继承它。注意到，控制器的包名是controllers，这就是前面配置中的controllerBasePackage配置值。
28 | ```java
29 | package controllers;
30 |
31 | import com.et.mvc.Controller;
32 |
33 | public class ApplicationController extends Controller{
34 |
35 | }
36 | ```
37 | ```java
38 | package controllers;
39 |
40 | import com.et.mvc.TextView;
41 |
42 | public class HelloController extends ApplicationController{
43 | public TextView say(){
44 | return new TextView("hello,world");
45 | }
46 | }
47 | ```
48 |
49 | 三、至些，我们的Hello,World程序编写完毕，部署后在浏览器地址栏输入http://localhost:8080/helloworld/hello/say，将会输出hello,world字样。
50 |

/Wiki/multi_database.md:
--------------------------------------------------------------------------------
1 | ## ActiveRecord中同时访问多个数据库
2 |
3 | 我们先来看一下ActiveRecord（下简称AR）的基本配置：
4 |
5 | ```java
6 | domain_base_class=com.et.ar.ActiveRecordBase
7 |
8 | com.et.ar.ActiveRecordBase.driver_class=com.mysql.jdbc.Driver
9 | com.et.ar.ActiveRecordBase.url=jdbc:mysql://localhost/mydb
10 | com.et.ar.ActiveRecordBase.username=root
11 | com.et.ar.ActiveRecordBase.password=soft123456
12 | com.et.ar.ActiveRecordBase.pool_size=2
13 | ```
14 |
15 | 其中的配置项domain\_base\_class是我们域模型对象的基类，我们在定义模型类时必须让其继承ActiveRecordBase，AR将根据此找到对应的数据库连接。
16 |
17 | 如果我们想同时使用多个数据库，这时我们可以先定义二个基类：
18 |
19 | ```java
20 | public class Base1 extends ActiveRecordBase{
21 | }
22 | public class Base2 extends ActiveRecordBase{
23 | }
24 | ```
25 |
26 | 然后进行配置：
27 |
28 | ```java
29 | domain_base_class=models.Base1 models.Base2
30 |
31 | models.Base1.driver_class=com.mysql.jdbc.Driver
32 | models.Base1.url=jdbc:mysql://localhost/mydb1
33 | models.Base1.username=root
34 | models.Base1.password=soft123456
35 | models.Base1.pool_size=2
36 |
37 | models.Base2.driver_class=com.mysql.jdbc.Driver
38 | models.Base2.url=jdbc:mysql://localhost/mydb2
39 | models.Base2.username=root
40 | models.Base2.password=soft123456
41 | models.Base2.pool_size=2
42 | ```
43 |
44 | 我们只要让我们的模型类继承Base1或Base2，就能正确使用对应的数据库连接。如果那一天又要改回去连接一个数据库了，只要改一下这个activerecord.properties属性文件就OK了。
45 |
46 | AR中同时访问多个数据库时是不是很简单。
47 |
--------------------------------------------------------------------------------
/Wiki/plugin.md:
--------------------------------------------------------------------------------
1 | ## etmvc框架中的插件
2 |
3 | etmvc框架拥有一套插件体系结构，如果需要扩展某些功能，就可以通过插件来完成。etmvc框架在初始化时会扫描安装进来的插件，如果发现有插件就进行加载。
4 |
5 | 举个例子，在WEB应用程序中如若需要一个后台服务进程处理一些事情，则使用插件提供的机制可能很合适，又如，在需要整个WEB应用程序加载之前执行一些代码时，也可以利用插件来完成，因为插件的启动执行是在etmvc框架初始化时完成的。
6 |
7 | 编写插件分二个步骤：
8 |
9 | 1、编写插件实现代码，要求实现com.et.mvc.PlugIn接口，如：
10 |
11 | ```java
12 | public class RouteLoader implements PlugIn{
13 |
14 | @Override
15 | public void destroy() {
16 | }
17 |
18 | @Override
19 | public void init(PlugInContext ctx) {
20 | Route route = new Route("blog/$year/$month/$day", DefaultRouteHandler.class);
21 | route.setController("blog");
22 | route.setAction("show");
23 | RouteTable.addRoute(0, route);
24 | }
25 |
26 | }
27 | ```
28 |
29 | 其中init方法做一些初始化的工作，destroy作一些销毁的工作。
30 |
31 | 2、注册插件，在web.xml中增加一个plugin的参数：
32 |
33 | ```xml
34 |
35 | etmvc
36 | com.et.mvc.DispatcherFilter
37 |
38 | controllerBasePackage
39 | controllers
40 |
41 |
42 | viewBasePath
43 | /views
44 |
45 |
46 | plugin
47 | utils.RouteLoader
48 |
49 |
50 |
51 | etmvc
52 | /*
53 |
54 | ```
55 |
56 | plugin参数值为插件实现类的名称，如果有多个插件，则以“,”分开。
57 |
58 | 3、重启WEB容器，这样就能正确加载插件了。
59 |

/Wiki/route.md:
--------------------------------------------------------------------------------
1 | ## etmvc框架对URL路由的支持
2 |
3 | etmvc框架使用路由技术实现把URL映射到控制器类中的action方法上，典型的http://localhost:8080/xxx/user/show将映射到UserController类中的show方法上，实际上这个规则是允许改变的。etmvc框架将允许你自定义自已的匹配规则来映射你的控制器类及其行为，这就需要定义路由。
4 |
5 | 一个路由的定义由一些占位符组成，占位符由美元符后面跟着字母组成，如“$controller/$action/$id”，这是框架采用的默认路由。根据这个路由，下面的这些例子将被匹配：
6 |
7 | |URL| CONTROLLER| ACTION |ID |
8 | |:--|:----------|:-------|:--|
9 | |/user| UserController| index | |
10 | |/user/show| UserController| show | |
11 | |/blog/show/123| BlogController| show |123 |
12 |
13 |
14 | 如果没匹配到$action，则将默认使用index方法。
15 |
16 | 定义一个新的路由时，必须实例化Route，如下面的这个例子：
17 |
18 | ```java
19 | Route route = new Route("blog/$year/$month/$day", DefaultRouteHandler.class);
20 | route.setController("blog");
21 | route.setAction("show");
22 | RouteTable.addRoute(0, route);
23 | ```
24 |
25 | 其中我们定义了嵌入式变量$year,$month,$day，这个路由规划将能够映射到BlogController类中的方法：
26 |
27 | ```java
28 | public String show(int year, int month, int day) {
29 | return year + "-" + month + "-" + day;
30 | }
31 | ```
32 |
33 | 嵌入式变量将自动映射成方法的参数。
34 |
35 | 可以定义多个路由规则，匹配是顺序进行的，也将是在路由表中从第一个规则开始进行匹配，找到就按照这个路由查找控制器类和方法。
36 |
37 | 在上面的例子中，这些URL将会有如下的映射：
38 |
39 | |URL| CONTROLLER| ACTION |
40 | |:--|:----------|:-------|
41 | |/blog/2009/07/10| BlogController| show |
42 | |/user/list| UserController| list |
43 | |/product/show| ProductController| show |
44 |
45 |
46 | 利用路由技术可以提供非常优雅的URL，一看URL就知道是那个控制器类和方法在处理。
47 |
48 | 最后有一点需要注意的是：定义一个路由后必须将它加入路由表中，并且确保在应用程序启动时是可用的。
49 |

/Wiki/transaction.md:
--------------------------------------------------------------------------------
1 | ## ActiveRecord中使用事务
2 |
3 | ActiveRecord中模型对象调用的每个方法如save, destroy, create, update等都是原子的，都受事务保护。
4 |
5 | 如果需要保证多个数据操作在一个事务中，则需要使用事务控制，如下所示：
6 |
7 | ```java
8 | try {
9 | ActiveRecordBase.beginTransaction();
10 | //do something
11 | ActiveRecordBase.commit();
12 |
13 | } catch (Exception ex) {
14 | ActiveRecordBase.rollback();
15 | }
16 | ```
17 |
18 | 如上所示，ActiveRecord中的事务是通过beginTransaction, commit, rollback等方法进行控制的。

/Wiki/upload_download.md:
--------------------------------------------------------------------------------
1 | ## etmvc中进行上传和下载
2 |
3 | et-mvc上传文件是对Commons-fileupload组件的封装，所以使用时需要引入commons-fileupload.jar, commons-io.jar, commons-logging.jar三个包。
4 |
5 | 上传文件的第一步就是象下面一样创建一个multipart/form-data表单：
6 |
7 | ```html
8 | " method="POST" enctype="multipart/form-data">
9 |
10 |
11 |
12 | ```
13 |
14 | 然后编写控制器，定义上传的Action方法：
15 | ```java
16 | public class UploadController extends ApplicationController{
17 | public String doUpload(MultipartFile file) throws Exception{
18 | file.transferTo(new File("e:/temp/" + file.getOriginalFilename()));
19 | return file.getOriginalFilename()+":"+file.getSize();
20 | }
21 | }
22 | ```
23 |
24 | 需要下载文件时，可以使用BinaryView，如下所示：
25 |
26 | ```java
27 | public BinaryView download() throws Exception{
28 | BinaryView view = BinaryView.loadFromFile("e:/temp/arrow.gif");
29 | view.setContentType("image/gif");
30 | //view.setContentDisposition("attachment"); //下载
31 | return view;
32 | }
33 | ```
34 |
35 | 上传下载就介绍这些，看起来应该是比较简单的。
36 |
37 |
38 |
