如何将现有的Spring项目迁移到Spring Boot [英] How to migrate existing Spring project to Spring Boot
本文介绍了如何将现有的Spring项目迁移到Spring Boot的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试将现有的Spring项目迁移到Spring Boot。
在项目中已经使用过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启动时迁移的所有内容是：
I'm trying to migrate existing Spring project to Spring Boot. In project already used Spring Data JPA/Hibernate and simple DAO with JDBC (PostgreSQL used). In few states I found that all that I need to migrate on Spring boot, is:
- 添加必要的依赖项
- 添加入口点@SpringBootApplication
- 利润，这就是全部。
1）依赖关系：
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>${spring.boot.version}</version>
<type>pom</type>

</dependency>
</dependencies>
</dependencyManagement>

</dependency>
<dependency>

<artifactId>spring-boot-starter-jetty</artifactId>

</dependency>
使用dependencyManagment部分我有错误：
With dependencyManagment section I have error:

没有它：

2）入口点（我也尝试导入配置类，评论）：
2) entry point (I'm also tried to Import configuration classes, commented):
@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);
}
}
并且配置：
@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。使用现有的Jetty服务器配置启动Spring启动应用程序需要做什么？
I have no idea what I'm doing wrong. What do I need to do to start spring boot application with existing Jetty server configuration?
UPDATE
我修改了主要内容pom：

此外，我已经评论了Spring引导依赖项的所有标签。
mvc dependency：tree给出以下输出：
also, I've commented all tags for spring boot dependencies. mvc dependency:tree give the following output:

无论如何，我在应用程序启动时遇到同样的问题：
Anyway, I have the same issue at application startup:
Warning: SLF4J: Class path contains multiple SLF4J bindings.

推荐答案
问题解决了：我修复了依赖问题。应该使用，
Problem solved: I fixed the dependency issues. Should use,
@Configuration
@EnableAutoConfiguration
@ComponentScan
@Import(Config.class)
而不是 @SpringBootApplication 注释。
现在应用程序正在启动，但找不到配置文件这是另一个故事。
instead @SpringBootApplication annotation.
Now the application is getting booted, but cannot find config file which is another story.
这篇关于如何将现有的Spring项目迁移到Spring Boot的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
