SpringBoot+ES项目：1. 后端框架搭建

ゝ一世哀愁。 2021-11-04 10:16 317阅读 0赞

1.  首先利用IDEA生成maven项目基本框架  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2x0aGlyZG9uZWw_size_16_color_FFFFFF_t_70]
2.  建立config包，建立JPAConfig类，建立entity包存放实体类  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2x0aGlyZG9uZWw_size_16_color_FFFFFF_t_70 1]

@Configuration
    @EnableJpaRepositories(basePackages = "com.xunwu.repository")
    //@EnableJpaRepositories用来扫描和发现指定包及其子包中的Repository定义。
    public class JPAConfig {
        //配置数据源  利用@ConfigurationProperties设置数据源前缀，从application.properties中自动获取数据配置
        @Bean
        @ConfigurationProperties(prefix = "spring.datasource")
        public DataSource dataSource(){
        
            return DataSourceBuilder.create().build();
            
        }
        //实体类的管理工厂
        @Bean
        public LocalContainerEntityManagerFactoryBean entityManagerFactory(){
        
            HibernateJpaVendorAdapter jpaVendor = new HibernateJpaVendorAdapter();
            jpaVendor.setGenerateDdl(false);
    
            LocalContainerEntityManagerFactoryBean entityManagerFactory = new LocalContainerEntityManagerFactoryBean();
            
            entityManagerFactory.setDataSource(dataSource());
            entityManagerFactory.setJpaVendorAdapter(jpaVendor);
            entityManagerFactory.setPackagesToScan("com.xunwu.entity");
            return entityManagerFactory;
            
        }
        //设置事务管理类
        @Bean
        public PlatformTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) {
        
            JpaTransactionManager transactionManager = new JpaTransactionManager();
            
            transactionManager.setEntityManagerFactory(entityManagerFactory);
            
            return transactionManager;
        }
    }

Springboot应用中@EntityScan和@EnableJpaRepositories的用法:

@Value 取赋值详解与 @ConfigurationProperties 对比

Hibernate中使用Spring Data JPA

**3. 配置application.properties**

spring.datasource.driver-class-name=com.mysql.jdbc.Driver  
spring.datasource.url=jdbc:mysql://62.2x4.xx.7:3306/xunwu?useUnicode=true&characterEncoding=UTF-8&useSSL=false  
spring.datasource.username=root  
spring.datasource.password=Liu  
spring.jpa.show-sql=true 方便我们在开发过程中随时看到SQL语句，方便调试开发  
spring.jpa.hibernate.ddl-auto=validate使得hibernate只对SQL做格式验证，不做一些增删改的操作  
logging.level.org.hibernate.SQL=debug 把SQL打印调为debug之后SQL语句才能正常输出  
spring.session.store-type=hash\_map 设置会话存储类型为hashmap  
security.basic.enabled=false关闭httpbasic验证

4.运行  
命令行中执行如下命令运行

mvn spring-boot:run

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2x0aGlyZG9uZWw_size_16_color_FFFFFF_t_70 3]  
或者直接运行springboot主函数
