</body>
</html>二、标签列表分页
1、TagService接口
package net.zl.myblog.service;
import javassist.NotFoundException;
import net.zl.myblog.po.Tag;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import java.util.List;
/** *
*/
public interface TagsService {
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
Tag updateTag(Long id,Tag tag);//更新
void deleteTag(Long id);//删除
}2、TagServiceImpl服务实现类
package net.zl.myblog.service;
import javassist.NotFoundException;
import net.zl.myblog.dao.TagRepository;
import net.zl.myblog.po.Tag;
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.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import java.util.ArrayList;
import java.util.List;
/** * 功能：服务实现类
* 作者：周璐
* 日期：2021-06-13
*/
@Service
public class TagServiceImpl implements TagsService{
@Autowired
private TagRepository tagRepository;
@Transactional
@Override
public Tag saveTag(Tag tag) {
return tagRepository.save(tag);
}
@Transactional
@Override
public Tag getTag(Long id) {
return tagRepository.findById(id).orElse(null);
}
@Override
public Tag getTagByName(String name) {
return tagRepository.findByName(name);
}
@Transactional
@Override
public Page<Tag> listTag(Pageable pageable) {
return tagRepository.findAll(pageable);
}
@Transactional
@Override
public Tag updateTag(Long id, Tag tag) {
Tag t = tagRepository.findById(id).orElse(null);
if (t == null) {
throw new NotFoundException("不存在该标签");
}
BeanUtils.copyProperties(tag,t);
return tagRepository.save(t);
}
@Transactional
@Override
public void deleteTag(Long id) {
tagRepository.deleteById(id);
}
}3、TagRepository接口
package net.zl.myblog.dao;
import net.zl.myblog.po.Tag;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.domain.Pageable;
import java.util.List;
public interface TagRepository extends JpaRepository<Tag,Long> {
Tag findByName(String name);
}三、测试效果
登陆后点击标签按钮，实现跳转
点击新增按钮实现跳转
不输数据直接点击提交，弹出提示
输入重复的数据弹出提示信息
编辑按钮实现修改数据功能
删除按钮，实现删除数据功能
