问题描述

从Mybatis的Aop容器容器中获取mapper对象,获取成功

将mybatis的的mapper对象放入jfinal 的aop容器中,放入成功

但是从jfinal的Aop容器中获取对象是时出现错误

因为mybatis 的mapper对象是一个接口

java.lang.IllegalArgumentException: abstract class or interface can not be proxied

有没有其他解决办法可以解决该问题?

出现异常的代码

  /**
   * 将Mapper添加到Aop容器中
   * @param sqlSession
   */
  private void addMapperToAopContainer(SqlSession sqlSession) {
    MapperRegistry mapperRegistry = sqlSession.getConfiguration().getMapperRegistry();
    Collection<Class<?>> mappers = mapperRegistry.getMappers();
    for (Class c : mappers) {
      //c仅仅是一个接口,需要从sqlSession总获取代理类
      log.info("接口类c:{}", c);
      Object mapper = sqlSession.getMapper(c);
      log.info("代理类 mapper:{}", mapper);
      //Aop.inject(mapper);
      //AopManager.me().addMapping(c, mapper);
      AopManager.me().getAopFactory().inject(c,mapper);
      
      Object object = Aop.get(c);
      log.info("获取到的Object:{}",object);
    }
  
  }
