Question

我是春天和maven的新手，我确实有这个引用的应用程序https://spring.io/guides/gs/rest-service/ 我正在使用spring + maven。

我需要通过tomcat将输出转换为简单的html，目前它使用的是嵌入式Apache Tomcat 7。

    package hello;

public class Greeting {

    private final long id;
    private final String content;

    public Greeting(long id, String content) {
        this.id = id;
        this.content = content;
    }

    public long getId() {
        return id;
    }

    public String getContent() {
        return content;
    }
}


package hello;

import java.util.concurrent.atomic.AtomicLong;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class GreetingController {

    private static final String template = "Hello, %s!";
    private final AtomicLong counter = new AtomicLong();

    @RequestMapping("/greeting")
    public Greeting greeting(@RequestParam(value="name", defaultValue="World") String name) {
        return new Greeting(counter.incrementAndGet(),
                            String.format(template, name));
    }
}

这是使用spring boot的主要内容，在嵌入式Apache中运行。

    package hello;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

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

有人可以帮我这个！我需要的是没有嵌入式tomcat的简单Web服务。只需要正常的tomcat部署。

pom.xml如下所示。

Answer 1

将此添加到您的POM

<packaging>war</packaging>

并执行mvn install或mvn package

您将在目标文件夹中看到以xxx.war.original结尾的工件。那个可以直接部署到Tomcat。

编辑： - 根据以下评论进行更新。还需要进行以下更改。

@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);
    }

}

请参阅doc以获取评论部分中引用的更多详细信息。

问题的完美解决方案和代码

SpringBoot包含嵌入式Tomcat，因此POM.xml中不需要特殊配置

您的POM.xml应该是以下代码。我使用bootsample作为工件，因此休息都是一样的。

您的问候域对象。

    /**

import org.springframework.stereotype.Component;

/**

 */
@Component
public class Greeting {

    private final long id;
    private final String content;

    public Greeting(long id, String content) {
        this.id = id;
        this.content = content;
    }

    public long getId() {
        return id;
    }

    public String getContent() {
        return content;
    }
}

您的控制器，在小心使用 @ResponseBody 注释之前，否则您将获得循环路径ViewResolver异常，因为SpringBoot设置了默认的viewResolver。此 @ResponseBody注释将跳过您的ViewResolver问题。

                    /**
                 * 
                 */

                import java.util.concurrent.atomic.AtomicLong;

                import org.springframework.boot.SpringApplication;
                import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
                import org.springframework.stereotype.Controller;
                import org.springframework.web.bind.annotation.RequestMapping;
                import org.springframework.web.bind.annotation.RequestParam;
                import org.springframework.web.bind.annotation.ResponseBody;
                /**
                 * @author Praveen
                 *
                 */
                @Controller
                @EnableAutoConfiguration
                @ResponseBody
                //@ComponentScan
                public class SimpleController {
                    private static final String template = "Hello, %s!";
                    private final AtomicLong counter = new AtomicLong();
                    @RequestMapping("/greeting")

                    public Greeting greeting(@RequestParam(value="name", defaultValue="World") String name) {
                        return new Greeting(counter.incrementAndGet(),
                                            String.format(template, name));
                    }



                    public static void main(String[] args) throws Exception {

                        SpringApplication.run(SimpleController.class, args);
                    }
                }

请使用Maven目标，如下图所示。你的maven目标应该是 mvn clean package spring-boot：run -e
执行此操作后，嵌入式tomcat将运行，您可以找到成功的输出。
成功记录
此外，您可以参考此链接Spring-boot reference documentation。为您的WAR / JAR创建问题。
