一、博客分页查询
1，新建BlogService接口

package net.zl.myblog.service;


import net.zl.myblog.po.Blog;
import net.zl.myblog.vo.BlogQuery;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;

import java.util.List;
import java.util.Map;


/**
 *
 */
public interface BlogService {
    Blog getBlog(Long id);//根据id查询
    Page<Blog> listBlog(Pageable pageable, Blog blog);//分页查询
    Blog saveBlog(Blog blog);//新增
    Blog updateBlog(Long id,Blog blog);//更新
    void deleteBlog(Long id);//删除
}

2，新建BlogRepository接口

package net.zl.myblog.dao;


import net.zl.myblog.po.Blog;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.JpaSpecificationExecutor;



import java.util.List;

/**
 * 
 */
public interface BlogRepository extends JpaRepository<Blog, Long>, JpaSpecificationExecutor<Blog> {
}

3，新建BlogServiceImpl.java类

package net.zl.myblog.service;


import net.zl.myblog.NotFoundException;
import net.zl.myblog.dao.BlogRepository;
import net.zl.myblog.po.Blog;
import net.zl.myblog.po.Type;
import net.zl.myblog.util.MarkdownUtils;
import net.zl.myblog.util.MyBeanUtils;
import net.zl.myblog.vo.BlogQuery;
import org.springframework.beans.BeanUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageRequest;
import org.springframework.data.domain.Pageable;
import org.springframework.data.domain.Sort;
import org.springframework.data.jpa.domain.Specification;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import javax.persistence.criteria.*;
import java.util.*;

/**
 *
 */
@Service
public class BlogServiceImpl implements BlogService {


    @Autowired
    private BlogRepository blogRepository;

    //根据id查询
    @Override
    public Blog getBlog(Long id) {
        return blogRepository.findById(id).orElse(null);
    }

    @Transactional
    @Override
    public Blog getAndConvert(Long id) {
        Blog blog=blogRepository.findById(id).orElse(null);
        if(blog==null){
            throw new NotFoundException("该博客不存在");
        }
        Blog b=new Blog();
        BeanUtils.copyProperties(blog,b);
        String content=b.getContent();
        b.setContent(MarkdownUtils.markdownToHtmlExtensions(content));

        blogRepository.updateViews(id);
        return b;
    }

    //分页动态查询
    @Override
    public Page<Blog> listBlog(Pageable pageable, BlogQuery blog) {
        return blogRepository.findAll(new Specification<Blog>() {
            @Override
            public Predicate toPredicate(Root<Blog> root, CriteriaQuery<?> cq, CriteriaBuilder cb) {
                List<Predicate> predicates = new ArrayList<>();
                if (!"".equals(blog.getTitle()) && blog.getTitle() != null) {
                    predicates.add(cb.like(root.<String>get("title"), "%"+blog.getTitle()+"%"));
                }
                if (blog.getTypeId() != null) {
                    predicates.add(cb.equal(root.<Type>get("type").get("id"), blog.getTypeId()));
                }
                if (blog.isRecommend()) {
                    predicates.add(cb.equal(root.<Boolean>get("recommend"), blog.isRecommend()));
                }
                cq.where(predicates.toArray(new Predicate[predicates.size()]));
                return null;
            }
        },pageable);
    }

    @Override
    public Page<Blog> listBlog(Pageable pageable) {
        return blogRepository.findAll(pageable);
    }

    @Override
    public Page<Blog> listBlog(Long tagId, Pageable pageable) {
        return blogRepository.findAll(new Specification<Blog>() {
            @Override
            public Predicate toPredicate(Root<Blog> root, CriteriaQuery<?> cq, CriteriaBuilder cb) {
                Join join= root.join("tags");
                return cb.equal(join.get("id"),tagId);
            }
        },pageable);
    }

    @Override
    public Page<Blog> listBlog(String query, Pageable pageable) {
        return blogRepository.findByQuery(query,pageable);
    }

    @Override
    public List<Blog> listRecommendBlogTop(Integer size) {
        Sort sort=Sort.by(Sort.Direction.DESC,"updateTime");
        Pageable pageable = PageRequest.of(0, size, sort);
        return blogRepository.findTop(pageable);
    }

    @Override
    public Map<String, List<Blog>> archiveBlog() {
        List<String> years=blogRepository.findGroupYear();
        TreeMap<String,List<Blog>> map=new TreeMap<>((o1,o2)->Integer.parseInt(o2)-Integer.parseInt(o1));
//        Map<String, List<Blog>> map =new LinkedHashMap<>();
        for (String year : years){
            map.put(year,blogRepository.findByYear(year));
        }
        return map;
    }

    @Override
    public long countBlog() {
        return blogRepository.count();
    }

    //新增
    @Transactional
    @Override
    public Blog saveBlog(Blog blog) {
        if(blog.getId()==null){
            blog.setCreateTime(new Date());
            blog.setUpdateTime(new Date());
            blog.setViews(0);//浏览次数
        }else {
            blog.setUpdateTime(new Date());
        }
        return blogRepository.save(blog);
    }
    //更新
    @Transactional
    @Override
    public Blog updateBlog(Long id, Blog blog) {
        Blog b=blogRepository.findById(id).orElse(null);
        if (b == null) {
            throw new NotFoundException("该博客不存在");
        }
        BeanUtils.copyProperties(blog,b, MyBeanUtils.getNullPropertyNames(blog));
        b.setUpdateTime(new Date());
        return blogRepository.save(b);
    }
    //删除
    @Transactional
    @Override
    public void deleteBlog(Long id) {
        blogRepository.deleteById(id);
    }


}

4、修改BlogController

package net.zl.myblog.web.admin;


import net.zl.myblog.po.Blog;
import net.zl.myblog.po.User;
import net.zl.myblog.service.BlogService;
import net.zl.myblog.service.TagService;
import net.zl.myblog.service.TypeService;
import net.zl.myblog.vo.BlogQuery;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Pageable;
import org.springframework.data.domain.Sort;
import org.springframework.data.web.PageableDefault;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.mvc.support.RedirectAttributes;

import javax.servlet.http.HttpSession;


/**
 * blogs控制器
 */
@Controller
@RequestMapping("/admin")
public class BlogController {

    @Autowired
    private BlogService blogService;


    @GetMapping("/blogs")
    public String blogs(@PageableDefault(size = 3,sort = {"updateTime"},direction = Sort.Direction.DESC)
                                Pageable pageable, Blog blog, Model model){
        model.addAttribute("page",blogService.listBlog(pageable,blog));
        return “admin/blogs";
    }

}

5、修改blogs.html

            });
        }
    </script>
</body>
</html>

6、渲染表单
在这里插入图片描述

7,链接数据库

链接成功

9、修改typeService

package net.zl.myblog.service;


import net.zl.myblog.po.Type;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;

import java.util.List;


/**
 * 分类服务
 */
public interface TypeService {

    Type saveType(Type type);//新增

    Type getType(Long id);//根据id查询

    Type getTypeByName(String name);//根据名称来查询

    Page<Type> listType(Pageable pageable);//分布查询

    List<Type> listType();

    Type updateType(Long id, Type type);//根据id修改

    void deleteType(Long id);//删除
}

10、实现接口方法
在这里插入图片描述
11、运行，查看结果
出现空指针错误
新建一个查询类BlogQuery

package net.zl.myblog.vo;

/**
 *查询类
 */
public class BlogQuery {

    private String title;
    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

package net.zl.myblog.service;


import net.zl.myblog.po.Blog;
import net.zl.myblog.vo.BlogQuery;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;

import java.util.List;
import java.util.Map;


/**
 *
 */
public interface BlogService {
    Blog getBlog(Long id);//根据id查询
    Page<Blog> listBlog(Pageable pageable, BlogQuery blog);//分页查询
    Blog saveBlog(Blog blog);//新增
    Blog updateBlog(Long id,Blog blog);//更新
    void deleteBlog(Long id);//删除
}

修改BlogController.java

package net.zl.myblog.web.admin;


import net.zl.myblog.po.Blog;
import net.zl.myblog.po.User;
import net.zl.myblog.service.BlogService;
import net.zl.myblog.service.TagService;
import net.zl.myblog.service.TypeService;
import net.zl.myblog.vo.BlogQuery;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Pageable;
import org.springframework.data.domain.Sort;
import org.springframework.data.web.PageableDefault;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.mvc.support.RedirectAttributes;

import javax.servlet.http.HttpSession;


/**
 * blogs控制器
 */
@Controller
@RequestMapping("/admin")
public class BlogController {
    private static final String INPUT = "admin/blogs-input";
    private static final String LIST = "admin/blogs";
    private static final String REDIRECT_LIST = "redirect:/admin/blogs";
    @Autowired
    private BlogService blogService;
    @Autowired
    private TypeService typeService;
    @Autowired
    private TagService tagService;

    @GetMapping("/blogs")
    public String blogs(@PageableDefault(size = 3,sort = {"updateTime"},direction = Sort.Direction.DESC)
                                Pageable pageable, BlogQuery blog, Model model){
        model.addAttribute("types",typeService.listType());
        model.addAttribute("page",blogService.listBlog(pageable,blog));
        return LIST;
    }

    @PostMapping("/blogs/search")
    public String search(@PageableDefault(size = 5, sort = {"updateTime"}, direction = Sort.Direction.DESC) Pageable pageable,
                         BlogQuery blog, Model model) {
        model.addAttribute("page", blogService.listBlog(pageable, blog));
        return "admin/blogs :: blogList";
    }
   
}

修改BlogServiceImpl.java
在这里插入图片描述
效果

二、博客新增
1、修改新增页面

 */
public interface TagService {

    Tag saveTag(Tag tag);//新增
    Tag getTag(Long id);//查询
    Tag getTagByName(String name);//根据名称查询
    Page<Tag> listTag(Pageable pageable);//分页查询
    List<Tag> listTag();
