1.说明
本文基于SpringBoot集成MyBatis-Plus代码生成器,
把原来生成Entity、Mapper、Mapper XML、Service、Controller等各个模块的代码，
修改为不使用Mapper作为名称，
而使用Dao作为名称，
下面给出代码生成器的代码。
2.代码修改点
// 1.全局配置
GlobalConfig gc = new GlobalConfig();
gc.setMapperName("%sDao");
// 3.包配置
PackageConfig pc = new PackageConfig();
pc.setMapper("dao");
// 4.自定义配置
focList.add(new FileOutConfig(templatePath) {
@Override
public String outputFile(TableInfo tableInfo) {
// 自定义输出文件名 ， 如果你 Entity 设置了前后缀、此处注意 xml 的名称会跟着发生变化
return projectPath + "/src/main/resources/mapper/" + tableInfo.getMapperName() + StringPool.DOT_XML;
}
});
3.生成文件
在工程中看到新生成如下文件：
src/main/resources/mapper/RoleDao.xml
src/main/java/com/yuwen/demo/entity/Role.java
src/main/java/com/yuwen/demo/dao/RoleDao.java
src/main/java/com/yuwen/demo/service/RoleService.java
src/main/java/com/yuwen/demo/service/impl/RoleServiceImpl.java
src/main/java/com/yuwen/demo/controller/RoleController.java
