spring boot异常积累

1、异常:Error resolving template "xxx", template might not exist or might not be accessible...解决办法

解决办法:在报出这个异常的方法上添加注解@ResponseBody

加上 @ResponseBody 后,会直接返回 json 数据

2、Field xxMapper in XXXXXX requried a bean of type ‘XXXMapper’ that could not be found ...解决办法

@Component
public interface XXXDepMapper{
    @InsertProvider(...)
     int insertXXX(....);           
}

解决办法:springboot和mybatis整合中,组件需要在配置中设置@MapperScan扫描包

@Confuguration
@EnableTransactionManagement
@MapperScab(vasePackages={"xxxxx.mapper"},sqlSessionFactoryRef="")
public class PostgressConfiguraction{
    ....      
}

 3、server.servlet-path:应用上下文路径,项目路径是构成url地址的一部分

  springboot版本更新后从server.context-path改成了server.servlet-path
