org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.taotao.mapper.T

解决方法：

1、命名空间错误（解决办法：利用对比工具对比MAPPER.XML, POM.XML文件）

2

• 在用maven配置mybatis环境时出现此BindingExceptiony异常，发现在classes文件下没有mapper配置文件，应该是maven项目没有扫描到mapper包下的xml文件，
  在pom.xml中加入一下代码可以解决：

      
      
        
        src/main/java  
          
          **/*.xml  
          
        

        
      
            src/main/resources
      
      
  

3、环境：spring3.1.1+mybatis3.2.8+mybatis-spring1.2.3 

SpringMVC + MyBatis整合，出现下面的错误:

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): org.com.mars.dao.test.UserDao.queryUserById

可能的原因是：

3.1. 请检查mapper.xml文件路径是否配置正确。

3.2. mapper.xml中的namespace 问题。

值应该是*Dao.java
