| 功能/配置项 | Spring XML配置方式 | Spring Boot注解方式 |
| 定义Bean | xml <bean id="myBean" class="com.example.MyBean"/> | java @Bean public MyBean myBean() { return new MyBean(); } |
| 注入Bean | xml <bean id="myBean" class="com.example.MyBean"> <property name="dependency" ref="dependencyBean"/> </bean> | java @Autowired private DependencyBean dependency; |
| 配置数据源 | xml <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.cj.jdbc.Driver"/> <property name="url" value="jdbc:mysql://localhost:3306/mydb"/> <property name="username" value="root"/> <property name="password" value="password"/> </bean> | java @Configuration @EnableAutoConfiguration @ComponentScan public class Application { @Bean @ConfigurationProperties(prefix = "spring.datasource") public DataSource dataSource() { return DataSourceBuilder.create().build(); } } |
| 配置事务管理 | xml <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"/> </bean> <tx:annotation-driven transaction-manager="transactionManager"/> | java @EnableTransactionManagement @Configuration public class AppConfig { @Bean public PlatformTransactionManager transactionManager(DataSource dataSource) { return new DataSourceTransactionManager(dataSource); } } |
| 配置JPA | xml <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="packagesToScan" value="com.example.entity"/> <property name="jpaVendorAdapter"> <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"/> </property> </bean> <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory"/> </bean> <tx:annotation-driven transaction-manager="transactionManager"/> | java @SpringBootApplication @EnableJpaRepositories(basePackages = "com.example.repository") public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } } |
| 配置MVC | xml <mvc:annotation-driven/> <context:component-scan base-package="com.example.controller"/> | java @SpringBootApplication @ComponentScan(basePackages = "com.example.controller") public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } } |
| 配置属性文件 | xml <context:property-placeholder location="classpath:application.properties"/> | java @SpringBootApplication @PropertySource("classpath:application.properties") public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } } |
| 配置AOP | xml <aop:aspectj-autoproxy/> <bean id="myAspect" class="com.example.MyAspect"/> | java @EnableAspectJAutoProxy @Configuration public class AppConfig { @Bean public MyAspect myAspect() { return new MyAspect(); } } |
