将 spring boot jar 转换为 war

Question

我开发了一个 Spring Boot 项目。现在我的要求是将jar包转换成war。 1.我把罐子变成了战争。转换后，我将war部署到tomcat服务器并尝试访问web服务。

@EnableAsync
@RestController
@EnableAutoConfiguration
@SpringBootApplication
@ComponentScan(basePackages="com.app.sensiple")
public class SensipleApplication extends SpringBootServletInitializer {

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



    public static void main(String[] args) {
        SpringApplication.run(SensipleApplication.class, args);
    }
    @RequestMapping("/test")
    String test() {
        return "This is test and it's Working fine!";
    }

上面的网址工作正常。

1. 我的应用程序包含不同的包，例如 Controller、Service 和 Repo。我添加了我的项目结构的屏幕截图。

2. 问题是我无法访问控制器包中的服务。我需要为此配置调度程序 Servlet 吗？？？？ .有人请帮帮我吗？

Answer 1

在 Spring Boot 中将 JAR 转换为 WAR 需要 3 个步骤：

1. 将包装改为战争
2. 将嵌入式 tomcat 标记为已提供。
3. 扩展 SpringBootServletInitializer 并覆盖 configure() 方法。

我已经使用下面给出的网站（逐步解释）将 jar 转换为 spring boot。

Answer 2

如果你使用的是 maven，你可以在 pom.xml 打包中注明

<packaging>war</packaging>
        <!-- ... -->
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-tomcat</artifactId>
                <scope>provided</scope>
            </dependency>
            <!-- ... -->
        </dependencies>

接下来你需要提供一个 SpringBootServletInitializer 子类并重写它的 configure 方法。

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

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

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }

}
