原因：服务器依赖的包javax/annotation/security/DenyAll不存在，没有加载成功！
可能是你的项目使用了Spring Security（Spring 安全框架），包javax/annotation/security/DenyAll默认是不加载的。

自动注入：@Autowired SchoolManagerAction schoolManagerAction; //根据类型自动注入

修改：@Autowired
 @Qualifier("schoolManagerAction") //根据名字注入
 Object schoolManagerAction;

 

 原因：代理是自动实现接口HasBeenInstrumented【

public class SchoolClassManagerAction
  implements HasBeenInstrumented{ } 】成为HasBeenInstrumented接口的实现类。

所以无法完成自动注入

 

 

 

错误三：？？插入数据库主键或唯一键重复

原因：mapper配置文件一般会有很多个。我们把mapper.xml 配置到SqlMapConfig.xml 里。

如：

SqlMapConfig.xml 文件：

<!-- 课程表内容 -->
  <mapper
   resource="com/superschool/resource/mybatis/sqlmap/SchoolCurriculumContentMapper.xml" />
  <!-- 课程表 -->
  <!-- <mapper resource="com/superschool/resource/mybatis/sqlmap/SchoolCurriculumMapper.xml"
   /> -->
  <!-- 试卷内容 -->
  <mapper
   resource="com/superschool/resource/mybatis/sqlmap/SchoolExaminationPaperMapper.xml" />
  <!--考试计划科目 -->
  <!-- <mapper resource="com/superschool/resource/mybatis/sqlmap/SchoolExamPlanCourseMapper.xml"
   /> -->
  <!-- 考试计划 -->
  <mapper
   resource="com/superschool/resource/mybatis/sqlmap/SchoolExamPlanMapper.xml" />
  <!-- 考试计划目标 -->
  <!-- <mapper resource="com/superschool/resource/mybatis/sqlmap/SchoolExamPlanTargetMapper.xml"
   /> -->

 

 但是当mapper  SchoolExamPlanCourseMapper.xml 文件还没有生成时（不存在时）而SqlMapConfig.xml里却配置了<mapper resource="com/superschool/resource/mybatis/sqlmap/SchoolExamPlanCourseMapper.xml"
   />对SchoolExamPlanCourseMapper.xml 进行了引用。系统解析sql映射文件时就无法找到指定的资源（resource="com/superschool/resource/mybatis/sqlmap/SchoolExamPlanCourseMapper.xml"
）所以产生次嵌套错误！
