基于spring boot项目构建可部署的WAR
我正在尝试从一个Spring启动项目创建一个WAR文件,它允许用户使用基于spring boot项目构建可部署的WAR,spring,tomcat,spring-boot,Spring,Tomcat,Spring Boot,我正在尝试从一个Spring启动项目创建一个WAR文件,它允许用户使用java-jarfilename运行该文件,并使用tomcat部署该文件 现在,我有以下配置: pom.xml <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xs
java-jarfilename
运行该文件,并使用tomcat部署该文件
现在,我有以下配置:
pom.xml

HelloController.java
package org.hello;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.boot.builder.SpringApplicationBuilder;
@SpringBootApplication
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
}
package org.hello;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.bind.annotation.RequestMapping;
@RestController
public class HelloController {
@RequestMapping("/")
public String index() {
return "Greetings from Spring Boot!";
}
}
通过这种配置,我可以在命令行中使用java-jarfilename
运行应用程序,但是当我在tomcat中部署war时,当我访问/page时,会得到一个404错误页面。(部署应用程序时不显示错误)
这里缺少什么?默认情况下,Spring Boot要求您的容器支持Servlet 3.0或更高版本。Tomcat6只支持Servlet2.5。最简单的选择是升级到Tomcat 7或8 如果你不能升级到Tomcat 7或8,那么仍然可以让你的应用程序运行。然而,这需要更多的努力。同样,您需要添加对
org.springframework.boot:springboot legacy
的依赖项,并添加具有以下内容的web.xml
:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

当应用程序部署到Tomcat时,您用来访问该应用程序的完整URL是什么?war文件的名称是什么?完整URL是http://server:8080/springapp-1.0.0
和war文件是springapp-1.0.0.war
。您说没有显示错误。还展示了什么?您应该在Tomcat的日志中看到输出,显示正在部署的war和正在启动的应用程序–Spring Boot的横幅等。在文件/var/log/tomcat6/catalina.out
中,部署后唯一的一行显示是:10月15日,2015 11:38:34 AM org.apache.catalina.startup.HostConfig deployWAR//INFO:Deploying web application archive springapp-1.0.0.war
我应该将这个web.xml文件放在我的项目树中的什么位置?可能是/src/main/resources?
