引起原因是因为缺少绑定

原始dao接口:

/*** MyBatis Generator* 根据动态条件获取列表总数（pageSize或pageNo传0不加入分页）contract*/@SelectProvider(type=ContractSqlProvider.class, method="pageTotal")int pageTotal(Contract record);

原始mapper.xml文件:

/*** 获取分页查询总条数*/public String pageTotal(Contract record) {SQL sql = new SQL();sql.SELECT("count(*)");sql.FROM("table");if (record.getContent() != null) {sql.WHERE("content = #{record.content,jdbcType=VARCHAR}");}if (record.getCreateTime() != null) {sql.WHERE("create_time = #{record.createTime,jdbcType=TIMESTAMP}");}if (record.getModifiedTime() != null) {sql.WHERE("modified_time = #{record.modifiedTime,jdbcType=TIMESTAMP}");}sql.WHERE("del_flag = 1");return sql.toString();}

修改后的正确写法为:
添加 @Param(“record”)

/*** MyBatis Generator* 根据动态条件获取列表总数（pageSize或pageNo传0不加入分页）contract*/@SelectProvider(type=ContractSqlProvider.class, method="pageTotal")int pageTotal(@Param("record") Contract record);

再重启动测试就OK!
欢迎大佬们留言评论,共同学习!!!感谢!!!
