调试了一天的bug  发现心不在焉敲出的代码真是  粗我屋百出 ，最后我总结了几点 mybiets 中错误的几个主要点

1。

mybits 的 接口类

public interface SalePlanMapper {

	public List <SalePlan>   <strong><span style="color:#ff6666;">list</span></strong>  (int uid);//根据不同用户的id的角色查询出不同的销售列表的内容
	

	
}
// 接口的方法名 应于 配置的文件名相同

//接口的返回类型应于配置文件的类型对应

//我的配置文件 结果集为 resultMap类型的，也主要是因为这个错的

//其他简单的错误 可能是因为  数据库中的字段和 配置文件或者 mybatis 的配置文件的字段不相同 导致的错误

2。mybaits 的配置文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper

	</select>
	<!--

解决 MyBatis 报错：Invalid bound statement (not found) 全方案

摘要：本文针对SpringBoot整合MyBatis时常见的"Invalid bound statement"错误进行了系统分析，指出该问题的本质是MyBatis无法找到对应的SQL映射语句。文章详细梳理了六大常见原因及解决方案：1）Mapper.xml的namespace配置错误；2）接口方法与XML标签id不匹配；3）实体类别名配置问题；4）Maven资源过滤缺失；5）XML文件存放路径不当；6）编译结果验证。同时提供了高级排查技巧，包括启用调试日志、使用@MapperScan注解等

会有一些包你明明@Autowired 但是还是找不到什么bean 导致你项目启动不了 解决方法一: 这个问题主要是因为项目拆包后，在原有的引用项目中无法找到对应的包的路径。在项目的Application启动文件里，使用@MapperScan注解，把当前的路径引用进去就可以了 解决方法二: 在相应的 @Autowired(required = false) 如下。所以，解决方法是让原来引用的项目可以找到资源的路径就可以了。明白真正靠得住的只有自己。

错误描述：问题在重构项目以后，之前的配置无法满足扫描到有bean的文件需要在启动类上添加注解通过写表达式的方式来进行扫描有bean的包即可完成运行可写多个使用“,”号隔开表达式书写规则：@ComponentScan注解的basePackages属性用于指定要扫描的包的路径。它可以接受字符串数组，表示需要扫描的一个或多个包路径。basePackages属性可以使用通配符表达式来扫描符合特定规则的包。如果需要扫描某些包中的所有类，包括不同的子包和头文件，则可以使用通配符表达式。

springboot 无法加载到mapper层，经过排查找到原因是：application.yml配置文件中配置的mysql连接问题，修改为下图格式后项目启动正常。启动springboot + mybatis的项目，启动类@SpringBootApplication注解，mapper层@mapper注解都存在，无遗漏。1、排查mapper层的注解是否存在缺漏，导致无法扫描到mapper层。2、排查service层的注解是否存在缺漏。3、排查数据库连接配置是否正确。

MyBatis报错`There is no getter for property`的映射配置问题
最新发布
shejizuopin的博客

摘要：MyBatis框架中常见的"There is no getter for property"错误通常由映射配置问题引起，主要包括属性名拼写错误、缺少getter方法、属性名与方法名不一致以及动态SQL表达式错误四种情况。解决方法需检查XML映射文件或注解中的属性引用是否正确，确保Java Bean中定义了符合规范的getter方法，并验证动态SQL中的OGNL表达式。通过系统性地检查这些关键点，开发者能有效解决该映射配置问题，提升应用稳定性。建议定期审计映射配置与Java Bean

2、UserService启动装配时变量名默认为实现类的名字userServiceImpl，实现类是UserServiceImpl类，而我们使用@Autowired注解时变量名为userService。（1）将当前模块的Dao类、Service类、Entity类、Controller类放在和XxxApplication启动类同一目录下或者子目录下。3、由于要自定义Dao类，这个自定义Dao类跟其他Dao类在类的定义上会不一样，如果自定义Dao类跟其他Dao类在类的定义上一样，会导致报错。

2.如果还是不能启动，则此时需要去检查bean注入容器的方式和引用bean的方式，对比这两种放式的注入bean名和引用bean名是否相同（如用@Service注释，bean名是类名转驼峰名的方式）1.根据提示信息里的bean名称和找不到的类名，检查该类是否具有把该类以报错bean名注入容器的操作，如没有添加注解或者xml文件注入容器，然后再去启动检查是否可以启动。3.如果最后还是不能启动成功，则注意检查引用bean的方式是否有限制扫描路径，限制路径下不存在要应用的bean名。
