mybatis-注解版＜2＞动态sql的bug

1、动态sql不支持单引号

@Select({"<script>",
		"SELECT mnh.mnh_mcn_num, mf.mf_name, mt.mt_name, ma.ma_name, mnh.mnh_plat_name, mnh.mnh_content",
		"FROM ( SELECT * FROM tbl_varys_m_mcnnotification_h h <where>", 
		"<if test = 'mcnNum != null and mcnNum != \'\' '>	h.mnh_mcn_num = #{mcnNum} </if>", 
		"<if test = 'belongDate != null'> AND h.mnh_belong_date = #{belongDate} </if>", 
		"<if test = 'platId != null '>	AND h.mnh_platid_fk = #{platId} </if>", 
		"<if test = 'content != null and content != \'\' '>	AND h.mnh_content LIKE concat('%',#{content},'%') </if>", 
		"</where>) mnh", 
		"LEFT JOIN tbl_varys_m_mcninfo mf ON mf.mf_mcnid = mnh.mnh_mcn_num", 
		"LEFT JOIN tbl_varys_m_organization og ON og.og_id = mf.mf_orgid_fk", 
		"LEFT JOIN tbl_varys_d_media_attr ma ON ma.ma_id = og.og_mediaattr_fk", 
		"LEFT JOIN tbl_varys_d_media_type mt ON mt.mt_id = mf.mf_mtlx_fk", 
		"<if test = 'mediaTypeId != null '> AND mf.mf_id = #{mediaTypeId} </if>",
		"limit #{startIndex} , #{pageSize}","</script>"
	})

启动报错:

2018-12-10 17:56:43.366 ERROR 11148 --- [           main] o.m.spring.mapper.MapperFactoryBean      : Error while adding the mapper 'interface com.guwukeji.varysstat.dao.MCNPlatNotificDao' to configuration.

修改之后：（将\’\’ 修改成\”\“）

@Select({"<script>",
		"SELECT mnh.mnh_mcn_num, mf.mf_name, mt.mt_name, ma.ma_name, mnh.mnh_plat_name, mnh.mnh_content",
		"FROM ( SELECT * FROM tbl_varys_m_mcnnotification_h h <where>",

		"<if test = 'belongDate != null'> AND h.mnh_belong_date = #{belongDate} </if>", 
		"<if test = 'platId != null '>	AND h.mnh_platid_fk = #{platId} </if>", 
		"<if test = 'content != null and content != \"\" '>	AND h.mnh_content LIKE concat('%',#{content},'%') </if>", 
		"</where>) mnh", 
		"LEFT JOIN tbl_varys_m_mcninfo mf ON mf.mf_mcnid = mnh.mnh_mcn_num", 
		"LEFT JOIN tbl_varys_m_organization og ON og.og_id = mf.mf_orgid_fk",
