首先,我是这个环境的新手.我以前开发过
Java,但不是应用程序服务器.从来没有这样做过,我以前从未使用过JBoss或WildFly.
我已经能够设置并运行WildFly服务器,并在127.0.0.1:9990访问它.当我部署.war文件时,服务器没有反应,我无法访问URL.
WildFly服务器确实声明我的部署成功并且处于活动状态,然后我尝试访问：127.0.0.1：8080 / RECAPP-API / rest / message / test,我得到404(找不到页面错误).
我正在使用Maven,所以首先,我的pom.xml：
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

我的JSONService.java：
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Response;
@Path("/message")
public class JSONService {
@GET
@Path("/{param}")
@Produces("application/json")
public Response printMessage(@PathParam("param") String msg) {
String result = "Restful example: " + msg;
return Response.status(200).entity(result).build();
}
}
最后,我的web.xml：
<?xml version="1.0" encoding="UTF-8"?>
<web-app

谢谢你的帮助.
解决方法
快速启动的最佳方法是使用此依赖项.
<dependency> <groupId>javax</groupId> <artifactId>javaee-api</artifactId> <version>7.0</version> <scope>provided</scope> </dependency>
并添加一个扩展应用程序类的类
@ApplicationPath("rest")
public class ConfigApp extends Application {
public ConfigApp(){
}
}
而已.没有web.xml更改(仅限不需要web.xml).
并使用host：port /< warname> / rest /< endpoint path>访问您的休息端点
