如何为 tomcat 配置专家战争插件



>我无法为Tomcat生成正确的WAR文件。

我正在使用MAVEN 3.6.1,Java 12.0.1和IDE Eclipse。当我在 eclipse(以 Spring 启动应用程序运行方式(中运行时,我的应用程序运行>工作正常,但问题是当我在生成它后尝试运行我的 WAR 文件时。

正在做java -jar .war,我得到:

Error: Could not find or load main class com.blw.linemanager.Application
Caused by: java.lang.ClassNotFoundException: com.blw.linemanager.Application

我正在谷歌搜索并阅读堆栈溢出,因为我发现了很多关于它的帖子,但仍然无法运行它。我做错了什么?

经过一些阅读,我发现我有一些如何配置 maven-war-plugin(我是对的吗?(,在 pom 中我做了一些更改,但它没有帮助。

也因为一开始我收到错误"没有主要清单属性"我添加了它,现在看起来像这样

Manifest-Version: 1.0
Created-By: Apache Maven ${maven.version}
Build-Jdk: ${java.version}

我的思维方式是错误的吗?我应该能够将.war文件作为java -jar .war运行,还是这是误解?

@SpringBootApplication
public class Application extends org.springframework.boot.web.support.SpringBootServletInitializer {
    public static void main(String [] args) {
        SpringApplication app = new SpringApplication(Application.class);
        app.run(args);
    }
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(Application.class);
    }
}

最好从这里获取一个工作的 spring 启动应用程序,以避免版本冲突等。对于war文件部署(例如,进入本地 tomcat(,应用程序必须扩展SpringBootServletInitializer

    @SpringBootApplication
    public class SpringBootTomcatApplication extends SpringBootServletInitializer {
      public static void main(String[] args) {
        SpringApplication.run(SpringBootTomcatApplication.class, args);
      }
      @Override
      protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(SpringBootTomcatApplication.class);
      }
    }

更改pom packagingwar

<packaging>war</packaging>

要生成war文件,您只需要spring-boot-maven-plugin

<build>
  <plugins>
    <plugin>
      <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
    </plugin>
  </plugins>
</build>

是的,你不需要maven-war-plugin.仅出于测试目的,让我们用@RestController注释我们的应用程序,并引入一个简单的端点:

    @RestController
    @SpringBootApplication
    public class SpringBootTomcatApplication extends SpringBootServletInitializer {
    ...
      @RequestMapping(value = "/")
      public String hello() {
        return "Hello World from Tomcat";
      }
    }

Local terminal中(在 eclipse Ctrl+Alt+T 中(,只需输入mvn package然后从文件夹中复制生成的war -target file,将其粘贴到本地 Tomcat 的 webapps 文件夹下,请求 http://localhost:8080/{您的应用程序名称},您应该会看到消息Hello World from Tomcat .现在,您可以添加所需的依赖项并继续编码。

在 pom 中添加带有版本详细信息的打包类型.xml例如

<packaging>jar</packaging>

<packaging>war</packaging>

然后,附加构建标记以定义jar/war的名称,例如,

<build>
    <finalName>YOUR-APP_NAME</finalName>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

然后,以目标运行应用程序

清洁包装

在目标文件夹中创建 jar/war。

将您的战争文件重命名为 ROOT,如 ROOT.war

最后一步是在tomcat网络应用程序文件夹中复制您创建的jar/war并启动tomcat。
