java - 如何将现有的 Spring 项目迁移到 Spring Boot-6ren

java - 如何将现有的 Spring 项目迁移到 Spring Boot

转载作者：搜寻专家更新时间：2023-10-30 21:32:38

我正在尝试将现有的 Spring 项目迁移到 Spring Boot。在项目中已经使用了 Spring Data JPA/Hibernate 和带有 JDBC 的简单 DAO(使用了 PostgreSQL)。在少数几个州，我发现我需要在 Spring boot 上迁移的所有内容是:

添加必要的依赖
添加入口点@SpringBootApplication
利润，仅此而已。

1) 依赖:

<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>${spring.boot.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

        </dependencies>
    </dependencyManagement>
<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.9.4</version>
    </dependency>
<dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-jpa</artifactId>
            <version>2.0.5.RELEASE</version>
        </dependency>
<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
            <version>1.4.7.RELEASE</version>
        </dependency>
<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jetty</artifactId>
            <version>1.4.7.RELEASE</version>
        </dependency>

使用 dependencyManagment 部分我有错误:

Exception in thread "main" java.lang.NoSuchMethodError: org.springframework.data.repository.config.RepositoryConfigurationSource.getAttribute(Ljava/lang/String;)Ljava/util/Optional;

    at org.springframework.boot.SpringApplication.run(SpringApplication.java:1107)
    at ru.testproject.BootConfiguration.main(BootConfiguration.java:26)

没有它:

    at org.springframework.boot.context.embedded.EmbeddedWebApplicationContext.onRefresh(EmbeddedWebApplicationContext.java:137)

2)入口点(我也试过导入配置类，评论):

@SpringBootApplication
//@Import({DatabaseConfig.class, WebMvcConfig.class, WebAppConfig.class, WebSecurityConfig.class, WebServiceConfig.class})
public class BootConfiguration extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(BootConfiguration.class, args);
//        SpringApplication.run(new Class<?>[] {BootConfiguration.class, DatabaseConfig.class, WebMvcConfig.class, WebAppConfig.class, WebSecurityConfig.class, WebServiceConfig.class}, args);
    }

    @Bean
    public JettyEmbeddedServletContainerFactory jettyEmbeddedServletContainerFactory() {
        JettyEmbeddedServletContainerFactory jettyContainer =
                new JettyEmbeddedServletContainerFactory();

        jettyContainer.setPort(9000);
        jettyContainer.setContextPath("");
        return jettyContainer;
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(BootConfiguration.class);
    }
}

和配置:

@Configuration
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
@EnableJpaRepositories(basePackages = {
        "ru.testproject.hibernate"
})
@EnableTransactionManagement
@PropertySource("classpath:application.properties")
public class DatabaseConfig implements TransactionManagementConfigurer {

    @Bean
    public DataSource dataSource() {

        if (DB_TYPE_POSTGRESQL.equalsIgnoreCase(dbType)) {
            return postresqlDataSource();
        } else {
            return h2DataSource();
        }

    }

    @Bean
    public PlatformTransactionManager annotationDrivenTransactionManager() {
        return new JpaTransactionManager();
    }
}

我不知道我做错了什么。我需要做什么才能使用现有的 Jetty 服务器配置启动 spring boot 应用程序？

更新我修改了主 pom:

无论如何，我在应用程序启动时遇到了同样的问题:

最佳答案

问题已解决:我修复了依赖性问题。应该用，

@Configuration
@EnableAutoConfiguration
@ComponentScan
@Import(Config.class)

代替@SpringBootApplication注解。
现在应用程序正在启动，但找不到配置文件，这是另一回事。
