不需要配置log4j ， 调试打印ibatis执行的sql语句和参数

Posted 2021-02-02 leite

背景：如果不想通过配置log4j的方式来打印ibatis执行的sql语句和参数param，可以使用如下方法在控制台打印sql语句和参数

 

public static void main(String[] args) {
        try {

            //声明配置文件的名称（映射文件被定义在其中）

            String resource = "com/test/tele/bean/iBatis-config-test.xml";

            //利用工具类Resources来读取到配置文件

            Reader reader = Resources.getResourceAsReader(resource);

            //创建SqlMapClient接口的变量实例

            SqlMapClient sqlMap = SqlMapClientBuilder.buildSqlMapClient(reader);
            
            Map paramMap = new HashMap();
            paramMap.put("isDisabled","0"); 
            paramMap.put("belongType","1"); 


            List list = sqlMap.queryForList("T_Process.selectExtDeptInfoByMap", paramMap);
            //debug 获取动态运行时sql以及参数
            SqlMapExecutorDelegate delegate = ((ExtendedSqlMapClient) sqlMap).getDelegate();
            MappedStatement ms = delegate.getMappedStatement("T_Process.selectExtDeptInfoByMap");//这个getXXSQL就是你想要获取的，在xml文件中定义的sql语句的id
            Sql sql = ms.getSql();
            RequestScope requestScope = new RequestScope();
            requestScope.setStatement(ms);
            String sqlStr = sql.getSql(requestScope,paramMap);
          
            Object[] sqlParam = sql.getParameterMap(requestScope, paramMap).getParameterObjectValues(requestScope, paramMap);
            System.out.println("运行时sql为" + sqlStr);
            for (int i = 0; i < sqlParam.length; i++) {
                         System.out.println("第[" + (i + 1) + "]个参数为:" + sqlParam[i]);
            }
 

        } catch (Exception e) {

            e.printStackTrace();

            

        }
    }
