mybatis的parameterType使用map实现真正的sql随意写

在dao层给map赋值

纠正一下应该把dd作为传入而不是sbiId;

sqlMap中的parameterType="java.util.Map", 就 OK

        List<PatentExecute> pes = ipm.selectAllAimpatent();
        List<PatentExecute> pesList = new ArrayList<PatentExecute>();
        List<Assessment> ass = ipm.getAssessmentBySbiId(sbiId);

                                pesList.add(patentExecute);
                            }
                        }

        }

        /**
         * 上面的方法写了这么多其实不必
         * 一条sql就搞定
         * <select id="r" resultMap="BaseResultMap" parameterType="java.util.Map">
              select t3.* from sm_s_assessment t1
                left join SM_S_ASSESSMENT_PLAN t2
                    on t1.SASS_ID = t2.SASS_ID
                left join SM_PATENT_EXECUTE t3
                    on t2.SAD_ID = t3.SAD_ID
                where t1.SBI_ID = #{sbiId, jdbcType=INTEGER}
              </select>
              问题是我的resultMap中没有SBI_ID这个列,怎么办
              有办法, 注意到parameterType有没有比平时不一样没<select id="r" resultMap="BaseResultMap" parameterType="java.util.Map">
              呵呵, 就是parameterType="java.util.Map" ; 有了这个你可以在dao随意传递多少个参数, 不管下面的resultMap中有没有对应的列或属性
              注意的是dao里传参,
              Integer sbiId = 21;
            Map<String, Object> m = new HashMap<String, Object>();
            m.put("sbiId", sbiId);
            List<PatentExecute> selectList = sqlSession.selectList("PatentExecuteMapper.r", m);
              总结: 其实就是把parameterType平时使用的javaBean或四类八种换了 map, 原理是一样的
                       */
其实还可以把上面的sql写到 指标 的sqlmap 中resultMap返回PatentExecuteMapper.BaseResultMap即可那么parameterType也不必须使用map类型了

如:<select id="r" resultMap="PatentExecuteMapper.BaseResultMap" parameterType="java.util.Map">
              select t3.* from sm_s_assessment t1
                left join SM_S_ASSESSMENT_PLAN t2
                    on t1.SASS_ID = t2.SASS_ID
                left join SM_PATENT_EXECUTE t3
                    on t2.SAD_ID = t3.SAD_ID
                where t1.SBI_ID = #{sbiId, jdbcType=INTEGER}
   </select>

mybatis是不是特别灵活啊!
