我正在尝试使用带有gretty的spring-boot创建一个Web服务。在gradle中调用appStart
时效果很好,但在调用appStartWar
时会显示错误。
这是错误:

似乎找不到war文件中的主类,但com.example.server.Application
确实存在与路径WEB-INF/classes/com/example/server
的战争中
的build.gradle
apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'spring-boot'
apply plugin: 'org.akhikhl.gretty'
buildscript {
repositories {
mavenCentral()
jcenter()
}
dependencies {
classpath 'org.akhikhl.gretty:gretty:1.1.8'
classpath 'org.springframework.boot:spring-boot-gradle-plugin:1.2.2.RELEASE'
}
}
dependencies{
compile 'org.springframework.boot:spring-boot-starter-web:1.2.2.RELEASE'
providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'
providedCompile 'javax.servlet:javax.servlet-api:3.1.0'
}
gretty {
springBoot = true
springBootVersion = '1.2.2.RELEASE'
httpsEnabled = true
}
Application.java
@RestController
@SpringBootApplication
class Application extends SpringBootServletInitializer {
public static void main( String[] args ) {
SpringApplication.run( Application.class, args );
}
@Override
protected SpringApplicationBuilder configure( SpringApplicationBuilder builder ) {
return builder.sources( Application.class );
}
@RequestMapping( value = "test", method = RequestMethod.GET )
public String test() {
return "success";
}
}
任何帮助表示赞赏:)
这是我在Gitlab中的项目link
我试图直接将战争部署到tomcat-7,但也失败了。所以我认为这不是一个问题。

@RestController
@SpringBootApplication
class Application extends SpringBootServletInitializer
课程需要公开:
@RestController
@SpringBootApplication
public class Application extends SpringBootServletInitializer
在目前的形式中,它受包保护,无法通过反射进行实例化。 (默认情况下)
