404 Not found Spring boot war to Tomcat [英] 404 Not found Spring boot war to Tomcat
问题描述
我有 Spring Boot 应用程序.这适用于嵌入式服务器.我可以使用 Postman 来测试 API.
I have Spring boot applicatio. This works fine with embedded server. And i can use Postman to test API.
现在我想在 Tomcat 8 上部署它，我用 maven install 创建 root.war 文件并将其放入 Tomcat/webapps/我运行tomcat没有任何错误.但是当我使用与邮递员相同的网址时，它给我 404 未找到.
Now i want deploy this on Tomcat 8 i create root.war file with maven install
and put it to Tomcat/webapps/
I run tomcat without any errors. But when i use the same url as postman it gives me 404 not found.
我用于两者(嵌入式和 tomcat)的 url 示例:localhost:8080/auth/registration
Example of url i use for both(embedded and tomcat): localhost:8080/auth/registration
我尝试在 application.properties 中设置 server.context-path 但没有结果.
I've tried to set server.context-path in application.properties but no result.
我认为问题出在项目的配置上.
I believe that problem is in configuration of project.
这是我的 pom.xml

此外，我发现 Spring Boot 可以比 war 更好的方式编译为 JAR.如果在 jar 中编译时如何更改 pom.xml 更好.
Also i have found that spring boot can be compiled to JAR as better way than war. If it's better how to change pom.xml for compiling in jar.
所以我尝试按照下面的建议创建 jar.我用 java -jar 运行它并得到org.springframework.context.ApplicationContextException:无法启动嵌入式容器；嵌套异常是 org.springframework.beans.factory.BeanCreationException:在类路径资源 [org/springframework/boot/autoconfigure/web/EmbeddedServletContainerAutoConfiguration$EmbeddedTomcat.class] 中定义的名称为tomcatEmbeddedServletContainerFactory"的 bean 创建时出错:bean 初始化失败；嵌套异常是 org.springframework.beans.factory.UnsatisfiedDependencyException:创建名为 'org.springframework.boot.autoconfigure.web.HttpEncodingAutoConfiguration' 的 bean 时出错:通过构造函数参数 0 表示的不满足的依赖；嵌套异常是 org.springframework.beans.factory.BeanCreationException:创建名为spring.http.encoding-org.springframework.boot.autoconfigure.web.HttpEncodingProperties"的 bean 时出错:bean 初始化失败；嵌套异常是 java.lang.NoClassDefFoundError: javax/xml/bind/ValidationException
So i've tried to create jar as suggested below. I run this with java -jar and got
org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'tomcatEmbeddedServletContainerFactory' defined in class path resource [org/springframework/boot/autoconfigure/web/EmbeddedServletContainerAutoConfiguration$EmbeddedTomcat.class]: Initialization of bean failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.web.HttpEncodingAutoConfiguration': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'spring.http.encoding-org.springframework.boot.autoconfigure.web.HttpEncodingProperties': Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: javax/xml/bind/ValidationException

推荐答案
Step1:
向 pom.xml 添加/更新以下依赖项(范围为 provided)，以告诉 Spring Boot 不要使用其嵌入式 Tomcat.
Step1:
Add/Update the following dependency to pom.xml (scope as provided) in order to tell Spring Boot not to use its embedded Tomcat.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
步骤 2:
<properties>
<packaging>war</packaging>
</properties>
步骤 3:
SpringBootApplication 类应如下所示:
Step3:
SpringBootApplication class should look like below:
@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);
}
}
参考:创建可部署的战争文件 和 Maven 打包
