【jeecg-boot】异常：异常:org.apache.ibatis.binding.BindingException: Parameter 'userId' not found

异常

org.apache.ibatis.binding.BindingException: Parameter 'userId' not found

原因:

           mapper 文件userId映射异常,增加 @Param 即可，修改如下，SysAnnouncementMapper.java

解决

package org.jeecg.modules.system.mapper;

import java.util.List;
import org.apache.ibatis.annotations.Param;
import org.jeecg.modules.system.entity.SysAnnouncement;

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;

/**
 * @Description: 系统通告表
 * @Author: jeecg-boot
 * @Date:  2019-01-02
 * @Version: V1.0
 */
public interface SysAnnouncementMapper extends BaseMapper<SysAnnouncement> {

	
	List<SysAnnouncement> querySysCementListByUserId(Page<SysAnnouncement> page, @Param("userId")String userId, @Param("msgCategory")String  msgCategory);

}
