这就是全部错误

abel533 commented 7 years ago

Mapped Statements collection already contains value for com.youma.mapper.UserMapper.delete

delete方法和通用Mapper提供的重复了。

Diluka commented 7 years ago

要删掉xml里面那些mapper，那么现在问题来了，怎么让xml生成的时候就没得呢？ 而且生成的Mapper没有加上@Mapper注解，结果还是手动改了一番

abel533 commented 7 years ago

@Diluka 通用mapper插件屏蔽了这些方法。

那么哪里写多了呢？它生成完整的xml

abel533 commented 7 years ago

生成的xml里面有什么？正常就一个resultMap。。。你这个配置（targetRuntime="MyBatis3"）还有很多example相关的，你想去掉的是什么？

Diluka commented 7 years ago

我已经手动删了，它把所有东西都生成了，不知道是不是我xml配置错了

一样的错误。 mapper-locations: classpath*:/mappers//.xml 修改为 mapper-location[0]: classpath:/mappers//*.xml 后，可以启动，但是通用Mapper接口就没有初始化

wuyadong commented 6 years ago

更新mapper-boot-starter到最新的1.2.3，在不同环境下还是会出现。看来是初始化顺序随机导致的

wuyadong commented 6 years ago

@MapperScan 替换为 tk.mybatis.spring.annotation.MapperScan，mapper文件直接安装包名位置存放-- 利用默认位置扫描。看上去似乎解决了，3个环境都没出问题。
