7、渲染表单

8、链接数据库

链接测试链接成功

9、修改typeService

10、实现接口方法

11、运行，查看结果

出现空指针错误

说明此方式不对，换一种方式

新建一个查询类

package net.zjs.lrm.vo;/*** 功能：查询类* 作者：zjs* 日期：-06-16*/public class BlogQuery {private String title;//查询标题private Long typeId;private boolean recommend;public BlogQuery() {}public String getTitle() {return title;}public void setTitle(String title) {this.title = title;}public Long getTypeId() {return typeId;}public void setTypeId(Long typeId) {this.typeId = typeId;}public boolean isRecommend() {return recommend;}public void setRecommend(boolean recommend) {this.recommend = recommend;}}

修改BlogService接口修改BlogController.java 修改BlogServiceImpl.java 效果

二、博客新增

1、修改新增页面
