6 | 实体类中联合主键的字段需要用@MppMultiId注解修饰
7 | 如果需要在service使用多主键相关操作包括saveOrUpdateByMultiId和批量操作updateBatchByMultiId和saveOrUpdateBatchByMultiId，可以直接继承IMppService接口
8 | 9 | **优化分页插件实现在不分页时进行排序操作** 10 | 原生mybatisplus分页与排序是绑定的，mpp优化了分页插件，使用MppPaginationInterceptor插件
11 | 在不分页的情况下支持排序操作
12 | page参数size设置为-1可实现不分页取全量数据，同时设置OrderItem可以实现排序
13 | 14 | **自动填充优化功能 & 自动扫描Entity类构建ResultMap功能** 15 | 原生mybatisplus只能做%s+1和now两种填充，mybatisplus-plus在插入或更新时对指定字段进行自定义复杂sql填充。
16 | 需要在实体类字段上用原生注解@TableField设置fill=FieldFill.INSERT fill=FieldFill.UPDATE或fill=FieldFill.INSERT_UPDATE否则不会触发自定义填充
17 | mybatisplus-plus使用@InsertFill注解触发插入时，执行注解中自定义的sql填充实体类字段
18 | mybatisplus-plus使用@UpdateFill注解触发更新时，执行注解中自定义的sql填充实体类字段
19 | 还可以自动填充主键字段,解决原生mybatisplus不支持多个主键的问题
20 | 使用ColNameUtil.pn静态方法，获取实体类中读取方法对应的列名称
21 |
22 | 在xml中编写resultmap是件头痛的事，特别是表连接时返回的对象是多样的，如果不按照map返回，分别建resultmap工作量会翻倍。
23 | 使用@AutoMap注解entity实体类，就可以在应用启动时解析使用@TableField注解的字段，自动生成scan.mybatis-plus_xxxx为id的resultMap
24 | 可以在xml中直接配置使用这个resultMap实例
25 | 并且还支持继承关系，扫描实体子类会附加上父类的字段信息一起构建子类的resultmap
26 | 对于各种表连接形成的返回实体对象，可以通过继承来生成。通过扫描后自动构建各种resultmap，在xml中引用。
27 |
28 | 做连表查询时，输入参数往往不是单一的实体类，而是采用更灵活的Map对象，
29 | 但map中key参数的名称定义过于随便，可以使用接口定义常量。但原生mybatis在xml中调用静态类方法和变量时需要填写完整的包名不利于大量采用
30 | 是否可以像在mybatisplus中使用lambda表达式翻译entity中的列名称
31 | mpp做了封装支持xml的ognl中引入默认包名(为了兼容jdk11 mpp1.7.0的ognl默认包名功能已经删除)，并支持lambda定义列名称
32 | 例如xml使用以下语句引入map参数中create_time 33 | 原生方式
34 | ```` 35 | #{create_time} 36 | ```` 37 | mpp的默认包名引用接口常量方式(1.7.0此配置已经删除)
38 | 配置文件中mpp.utilBasePath可设置ognl默认包名
39 | ```` 40 | #{${@ColInfo@createTime}} 41 | ```` 42 | mpp的lambda方式(1.7.0中使用@com.MPP@col)
43 | ```` 44 | #{${@MPP@col("TestEntity::getCreateTime")}} 45 | ```` 46 | **从中央库引入jar** 47 | ```` 48 | 49 | com.github.jeffreyning 50 | mybatisplus-plus 51 | 1.7.5-RELEASE 52 | 53 | ```` 54 | 55 | 56 | 57 | **在实体类上设置@KeySequence，在插入时对id字段自动填充复杂计算值** 58 | ```` 59 | @KeySequence("select lpad(max(seqno)+3,10,'0') from test") 60 | @TableName(value = "test") 61 | public class TestEntity { 62 | @TableId(value = "id", type=IdType.INPUT) 63 | private Integer id;

363 | bean.setDataSource(dateSource); 364 | bean.setGlobalConfig(globalConfig); 365 | return bean.getObject(); 366 | } 367 | ``` 368 | 369 | _启动时报异常NoSuchFieldException: modifiers_ 370 | ``` 371 | org.springframework.beans.factory.BeanCreationException: 372 | Error creating bean with name 'com.github.jeffreyning.mybatisplus.conf.PlusConfig': 373 | Invocation of init method failed; nested exception is java.lang.NoSuchFieldException: modifiers 374 | ``` 375 | 应该是jdk11与自定义ognl加载机制不兼容导致的。 376 | mybatisplus-plus1.7.0删除了自定义ognl根路径功能，兼容jdk11。 377 | 378 | _报 not found column for 'id'_ 379 | mybatis-plus的问题，所有叫id的属性都自动注册为主键 380 | 1.7.2版本已经解决了此问题，mpp的多主键@MppMultiId可以和mp的单主键@TableId兼容，同时修饰同一个field 381 | 382 | _启动时日志中有mpp.entityBasePath is null skip scan result map_ 383 | 只是个提示不影响，不想看到提示，mpp.entityBasePath可以配置到entity的包如entityBasePath: com.github.jeffreyning.mybatisplus.demo.entity； 384 | 如果xml中有resultMap="scan.mybatis-plus_xxx"才需要配置mpp.entityBasePath 385 | 386 | _提示java.lang.RuntimeException: not found column for 'xxx'_ 387 | 是由于设置了@MppMultiId的字段没有同时设置@TableField(value = "xxx")导致的 388 | 389 | _使用@UpdateFill和@InsertFill自动填充时报错提示Cause: java.lang.IllegalArgumentException: argument type mismatch_ 390 | 由于对某些entity中的字段类型没有做转换如LocalDateTime导致自动填充的sql的返回值类型与entity字段类型不相符，mpp1.7.4版本已经解决了此问题，旧版本需修改entity字段类型与sql返回类型一致。 391 | 392 | _调用saveOrUpdateBatchByMultiId方法报错提示 java.lang.IllegalAccessError: tried to access field com.baomidou.mybatisplus.extension.service.impl.ServiceImpl.entityClass from class com.github.jeffreyning.mybatisplus.service.MppServiceImpl_ 393 | 是由于mybatis-plus3.5.5+兼容性造成的，需使用mpp1.7.5版本解决此问题 394 | 395 | _如何整合pagehelper插件_ 396 | 397 | mybatisplus本身有分页常见，如果一定要使用pagehelper插件的话，与原生的mybatisplus有冲突 398 | 解决方法为：使用以下代码加载pageHelper(版本为5.1.10) 399 | ``` 400 | @Bean 401 | ConfigurationCustomizer mybatisConfigurationCustomizer() { 402 | return new ConfigurationCustomizer() { 403 | @Override 404 | public void customize(Configuration configuration) { 405 | configuration.addInterceptor(new com.github.pagehelper.PageInterceptor());

414 | mybatisplus-plus1.7.4优化自动填充时的字段类型转换功能

416 | mybatisplus-plus1.7.2支持mpp的多主键@MppMultiId可以和mp的单主键@TableId兼容，同时修饰同一个field
