SpringMVC Hibernate与JPA使用教程

2022-12-09 10:24 开发作者：正怒月神

一、POM

说明：

1 spring boot标签中，是需要添加的架包

由于我的发布方式是tomcat，所以需要打包时过滤springboot中的tomcat

2 build标签中，是打包方式。这里可以不看

3 这里有一个jpa版本的问题。

由于之前使用的jpa版本很低。这导致和springboot2.7.2版本的jpa版本不匹配。

其中，jpa2.7.2版本的findOne方法没有了，改为了findById。

这导致调用基础dao的方法会报错：NoSuchMethod。

所以下面也提供了JPA的架包导入方式。如果JPA版本是匹配的，那直接使用下面注释的

spring-boot-starter-data-jpa

二、引入springMVC中的applicationContext.xml

1 先看一下springmvc中的xml

将其拷贝到springboot中的resources下

2 application.yml (springboot)

添加如下：

spring:
main:
allow-bean-definition-overriding: true

三、启动类

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.data.jpa.JpaRepositoriesAutoConfiguration;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.ImportResource;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
//过滤hibernate jpa的自动加载
@SpringBootApplication(exclude = {HibernateJpaAutoConfiguration.class})
//扫描包
@ComponentScan(basePackages={"com.kintech"},lazyInit=true)
//扫描jpa的dao
@EnableJpaRepositories(basePackages = {"com.kintech.dao.jpa"})
//扫描jpa 用到的entity
@EntityScan("com.kintech.model.domain")
//导入springmvc的applicationContext.xml
@ImportResource({"classpath:spring/applicationContext.xml"})
public class WebInvoiceApplication {
    public static void main(String[] args) {
        SpringApplication.run(WebInvoiceApplication.class, args);
    }
}
