springboot:使用pagehelper之后，无法添加自定义mybatis拦截器

1.实现自定义mybatis拦截器

@Component
@Intercepts({ @Signature(type = Executor.class, method = "update", args = { MappedStatement.class, Object.class }) })
public class MybatisInterceptor implements Interceptor {

// 略......

}

2.在web listener中添加这个拦截器

@Component
public class StartSysListener implements ApplicationListener<ContextRefreshedEvent> {

  private static Logger log = LoggerFactory.getLogger(StartSysListener.class);
  
  @Autowired
  private MybatisInterceptor mybatisInterceptor;
  @Autowired
  private List<SqlSessionFactory> sqlSessionFactoryList;


  @Override
  public void onApplicationEvent(ContextRefreshedEvent event) {

    this.addMyInterceptor();

  }

  private void addMyInterceptor() {
    log.debug("添加自定义Mybatis SQL拦截器.");
    for (SqlSessionFactory sqlSessionFactory : sqlSessionFactoryList) {
      sqlSessionFactory.getConfiguration().addInterceptor(mybatisInterceptor);
    }
  }

}

这种方式添加简单，易于使用。
