Spring+Mybatis的注解配置整合

跟之前的普通的XML配置有了许多的不同
总体来说我觉得注解配置简单一些
 
maven项目的pom.xml是真的又臭又长，就放到最后把
先把applicationContext.xml放上来
mysql的配置和log4j的配置

log4j.rootCategory=ERROR,stdout
log4j.logger.org.springframework=ERROR
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - <%m>%n

#mysql连接配置
driver=com.mysql.cj.jdbc.Driver
url=jdbc:mysql://localhost:3306/test0605?serverTimezone=Asia/Shanghai
username=root
password=614

pojo层

service层

package top.yibobo.service;
import org.apache.ibatis.annotations.*;
import top.yibobo.pojo.Article;
import java.util.List;
public interface ArticleService {
    List<Article> findAll();
    Article findById(@Param("id") int id);
    int addArticle (Article article);
    int updateArticle(Article article);
    int deleteArticle(@Param("id") int id);
}

 
最关键的 service实现

package top.yibobo.service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Isolation;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
import top.yibobo.dao.ArticleMapper;
import top.yibobo.pojo.Article;
import java.util.List;
@Service("articleService")
@Transactional(propagation = Propagation.NOT_SUPPORTED,readOnly = true)//不开启事务，只读
public class ArticleServiceImpl implements ArticleService {
    @Autowired//组件注解，自动绑定。把bean容器中叫articleMapper的自动绑定上来
    //@Resource(name = "articleMapper")
    private ArticleMapper articleMapper;
    @Override
    public List<Article> findAll() {
        return articleMapper.findAll();
    }
    @Override
    public Article findById(int id) {
        return articleMapper.findById(id);
    }
    @Transactional(propagation = Propagation.REQUIRED,
            isolation = Isolation.DEFAULT,rollbackFor = Exception.class)
    @Override
    public int addArticle(Article article) {
        return articleMapper.addArticle(article);
    }
    @Transactional(propagation = Propagation.REQUIRED,
            isolation = Isolation.DEFAULT,rollbackFor = Exception.class)
    @Override
    public int updateArticle(Article article) {
        return articleMapper.updateArticle(article);
    }
    @Transactional(propagation = Propagation.REQUIRED,
            isolation = Isolation.DEFAULT,rollbackFor = Exception.class)
    @Override
    public int deleteArticle(int id) {
        return articleMapper.deleteArticle(id);
    }
}

 
测试类

package top.yibobo.test;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import top.yibobo.pojo.Article;
import top.yibobo.service.ArticleService;
import java.util.List;
public class ArticleTest {
    @Test
    public void test1(){
        ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
        ArticleService articleService = ctx.getBean("articleService", ArticleService.class);
        List<Article> all = articleService.findAll();
        all.forEach(article -> System.out.println(article));
    }
}
