下面给大家介绍mybatis interceptor 处理查询参数及查询结果，具体代码如下所示：

/**

@Intercepts({
    @Signature(type=Executor.class,method="update",args={MappedStatement.class,Object.class}),
    @Signature(type=Executor.class,method="query",args={MappedStatement.class,Object.class,RowBounds.class,ResultHandler.class})
})
public class EncryptInterceptor implements Interceptor {
  public static final Logger logger = LoggerFactory.getLogger(EncryptInterceptor.class);
  @Override
  public Object intercept(Invocation invocation) throws Throwable {
    dealParameter(invocation);
    Object returnValue = invocation.proceed();
    dealReturnValue(returnValue);
    return returnValue;
  }
  //查询参数加密处理
  private void dealParameter(Invocation invocation) {
    MappedStatement statement = (MappedStatement) invocation.getArgs()[0];
    String mapperl = ConfigUtils.get("mybaits.mapper.path");
    String methodName = statement.getId().substring(statement.getId().indexOf(mapperl) + mapperl.length() + 1);
    if (methodName.startsWith("UserBaseMapper")){
      if(methodName.equals("UserBaseMapper.updateDriver")){
        ((Driver) invocation.getArgs()[1]).encrypt();
      }
    }
    logger.info("Mybatis Encrypt parameters Interceptor, method: {}, args: {}", methodName, invocation.getArgs()[1]);
  }
  //查询结果解密处理
  private void dealReturnValue(Object returnValue){
    if(returnValue instanceof ArrayList){
      List list = (ArrayList)returnValue;
      for(Object val: list){
        if(val instanceof Passenger){///
          //TODO
        }
        logger.info("Mybatis Decrypt result Interceptor, result object: {}", ToStringBuilder.reflectionToString(val));
      }
    }
  }
  @Override
  public Object plugin(Object target) {
    return Plugin.wrap(target, this);
  }
  @Override
  public void setProperties(Properties properties) {
  }
}

添加配置：

       
       
       
       
       
           
              
                  
                     dialect=hsqldb
                  
              
              
                  
                     property-key=property-value
