IDEA打包war部署到tomcat 404错误（tomcat配置正确）

IDEA打包war部署到tomcat 404错误（tomcat配置正确）

此问题状况可能满足以下条件的

1.本地使用gradle bootRun后访问地址正常

2.部署到tomcat后访问接口地址出现404错误

3.在tomcat项目中新建index.html可以访问

解决方案

1.gradle首先确认满足以下条件

buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.5.8.RELEASE")
}
}

apply plugin: 'war'
apply plugin: 'org.springframework.boot'
...

war {
baseName = 'projectname'
version =  '0.0.1'
}

repositories {
mavenCentral()
jcenter()
maven { url "http://repo.spring.io/libs-snapshot" }
}

dependencies {
compile("org.springframework.boot:spring-boot-starter-web")

//注意打包war此处是providedRuntime，不是compile
providedRuntime("org.springframework.boot:spring-boot-starter-tomcat")

...
}

2.Application.java文件需要修改成如下，用来告诉容器入口

@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);
}
}

之前我这边错误样例 如下，bootRun可以跑，但是tomcat就不行

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