mybatis interceptor 处理查询参数及查询结果的实例代码

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：

<bean id="sqlsessionfactory" class="org.mybatis.spring.sqlsessionfactorybean">
       <property name="typealiasespackage" value="com.xx.model"/>
       <property name="datasource" ref="datasource"/>
       <!-- 自动扫描mapping.xml文件 -->
       <property name="mapperlocations" value="classpath*:mybatis/*.xml"></property>
       <property name="plugins">
           <array>
              <bean class="com.github.pagehelper.pagehelper">
                  <property name="properties">
                     <value>dialect=hsqldb</value>
                  </property>
              </bean>
              <bean class="com.xx.interceptor.encryptinterceptor">
                  <property name="properties">
                     <value>property-key=property-value</value>
                  </property>
              </bean>
           </array>
       </property>
    </bean>
