我想在Springboot中创建一个简单的hello世界，如REST Application，并将其部署到JBOSS EAP 6.4。
我只有一个端点：
GET向/api/logparser请求并返回json
我可以设法建立一个war文件并在本地运行而没有任何问题。
我认为问题出在我的web.xml和上下文设置上，但我不知道是什么导致了错误。
我的项目如下：
build.gradle
plugins {
id 'org.springframework.boot' version '2.1.3.RELEASE'
id 'java'
id 'war'
}
apply plugin: 'io.spring.dependency-management'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'
repositories {
mavenCentral()
}
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-web'
providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
}
Application.java
package com.custom.logparser;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
我的控制器LogFileController.java
package com.custom.logparser;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class LogFileController {
@RequestMapping("/api/logparser/getlog")
public LogFile greeting() {
return new LogFile("logFileContent");
}
}
LogFile.java
package com.custom.logparser;
public class LogFile {
private final String content;
public LogFile(String content) {
this.content = content;
}
public String getContent() {
return content;
}
}
我已经创建了一个ServletInitializer.java
package com.custom.logparser;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
public class ServletInitializer extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
}
web.xml

Description:
An attempt was made to call the method javax.validation.Configuration.getDefaultParameterNameProvider()Ljavax/validation/ParameterNameProvider; but it does not exist. Its class, javax.validation.Configuration, is available from the following locations:
jar:file:/opt/jboss-eap/modules/system/layers/base/javax/validation/api/main/validation-api.jar!/javax/validation/Configuration.class
vfs:/content/logparser-web-service-0.0.1-SNAPSHOT.war/WEB-INF/lib/validation-api-2.0.1.Final.jar/javax/validation/Configuration.class
It was loaded from the following location:
jar:file:/opt/jboss-eap/modules/system/layers/base/javax/validation/api/main/validation-api.jar!/
