在tomcat中部署后无法访问Spring Boot应用程序 [英] Cannot access spring boot application after deployment in tomcat
问题描述
我已经使用Spring Boot创建了REST API.我正在使用gradle作为构建工具.我已经使用嵌入式容器测试了该应用程序,并且运行良好.我可以通过localhost:8080/foo/bar
访问我的应用程序.
I have created a REST API using Spring boot. I am using gradle as my build tool. I have tested the application using the embedded container and it is working fine. I am able to access my application at localhost:8080/foo/bar
.
现在,我已将其部署到tomcat,没有任何错误.
Now I have deployed it to tomcat without any error.
Mar 17, 2016 1:58:47 PM org.apache.catalina.startup.HostConfig deployWAR
INFO: Deploying web application archive /usr/local/apache-tomcat-7.0.65/webapps/foo.war
Mar 17, 2016 1:58:48 PM org.apache.catalina.startup.TldConfig execute
INFO: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.
Mar 17, 2016 1:58:48 PM org.apache.catalina.startup.HostConfig deployWAR
INFO: Deployment of web application archive /usr/local/apache-tomcat-7.0.65/webapps/foo.war has finished in 623 ms
但是我现在无法通过localhost:8080/foo/bar
访问该应用程序.我可以看到tomcat在localhost:8080
But I am now unable to access the application at localhost:8080/foo/bar
. I can see that tomcat is running at localhost:8080
这是build.gradle
文件.
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.3.3.RELEASE")
}
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'spring-boot'
apply plugin: 'war'
war {
baseName = 'foo'
}
repositories {
mavenCentral()
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
configurations{
providedRuntime
}
dependencies {
compile 'org.springframework.boot:spring-boot-starter-web'
providedRuntime("org.springframework.boot:spring-boot-starter-tomcat")
compile 'com.google.code.gson:gson:2.6.2'
compile 'org.springframework:spring-webmvc:4.2.5.RELEASE'
compile 'org.json:json:20151123'
providedRuntime 'javax.ws.rs:javax.ws.rs-api:2.0.1'
providedRuntime 'javax.servlet:javax.servlet-api:3.1.0'
providedRuntime 'javax.servlet:jstl:1.2'
testCompile("junit:junit")
}
task wrapper(type: Wrapper) {
gradleVersion = '2.11'
}
我有一个带有以下代码的application.properties
文件
I have an application.properties
file with the following code
server.context-path=/foo
并且我在控制器中的请求映射设置为
and my request mapping in controller is set to
@CrossOrigin
@RequestMapping("/bar")
public String bar(){
// Code
}
我尝试了中提到的内容发布,但这也无法正常工作.
I tried what is mentioned in this post, but that is also not working.
@SpringBootApplication
public class FooApplication {
public static void main(String[] args) {
SpringApplication.run(FooApplication.class, args);
}
// Used when deploying to a standalone servlet container
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(FooApplication.class);
}
}
推荐答案
要部署Spring Boot应用程序,您必须具有扩展org.springframework.boot.context.web.SpringBootServletInitializer
并覆盖org.springframework.boot.context.web.SpringBootServletInitializer.configure(SpringApplicationBuilder application)
To deploy a Spring Boot application you have to have a configuration class which extends org.springframework.boot.context.web.SpringBootServletInitializer
and overrides org.springframework.boot.context.web.SpringBootServletInitializer.configure(SpringApplicationBuilder application)
因此,当将应用程序部署在JEE Servlet容器中时,Spring Boot应用程序将被正确部署并提供服务.
So when the application is deployed in a JEE Servlet container Spring Boot application will be deployed and served properly.
示例
@Configuration
public class AppServletInitializer extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
}
Application.class
与main方法中SpringApplication.run(Application.class, args);
中的类相同
The Application.class
is same class as in SpringApplication.run(Application.class, args);
in the main method
