32 | 33 | //ArticleHandler.java文件 get方法 34 | public void get(String id){ 35 | //获取ID进行其他操作 36 | …… 37 | } 38 | ``` 39 | 这样在ArticleHandler中对应的get或者post方法中就会获取相应的参数。当然，你可以任意的使用正则表达式来配置你的URL 40 | 41 | 简单易用的数据库操作 42 | ---- 43 | ``` 44 | Options.DBURL = "jdbc:mysql://localhost:3306/test"; 45 | Options.DBDriver = "com.mysql.jdbc.Driver"; 46 | Options.DBUser = "root"; 47 | Options.DBPassword = "123456"; 48 | ``` 49 | 配置好数据库信息后，可以直接在Handler中使用DB中的静态方法进行操作。 50 | 具体的操作在DB中有说明。当然如果你想，可以使用任何你想用的ORM。当然，希望你能直接使用SQL，不想解释为什么。 51 | 52 | Hello World! 53 | ---- 54 | 看名字就知道了。让我们开始使用Web.Java吧！ 55 | 把源码包放到你的项目目录下面。 56 | 然后在main方法中加入 57 | ``` 58 | HttpServer.setPATH("/", new IndexHandler()); 59 | System.out.println("Listen 8080"); 60 | HttpServer.init(8080); 61 | ``` 62 | IndexHandler.java 63 | ``` 64 | public void get() { 65 | this.writer("Hello World!"); 66 | } 67 | ``` 68 | 现在Run it 浏览器打开就会看到你Writer的内容了。 69 | -------------------------------------------------------------------------------- /Web/Allocation.java: -------------------------------------------------------------------------------- 1 | package Web;
