*package main.java;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
//Sets the path to base URL + /hello
**@Path("/hello")**
public class Hello {
// This method is called if TEXT_PLAIN is request
@GET
@Produces(MediaType.TEXT_PLAIN)
public String sayPlainTextHello() {
return "Hello Jersey";
}
// This method is called if XML is request
@GET
@Produces(MediaType.TEXT_XML)
public String sayXMLHello() {
return "<?xml version=\"1.0\"?>" + "<hello> Hello Jersey" + "</hello>";
}
// This method is called if HTML is request
@GET
@Produces(MediaType.TEXT_HTML)
public String sayHtmlHello() {
return "<html> " + "<title>" + "Hello Jersey" + "</title>" + "<body><h1>" + "Hello Jersey" + "</body></h1>" + "</html> ";
}

答案 0 :(得分:0)
部署WAR文件时很少有人知道。
TRY:
从命令行或管理器应用程序重新部署WAR文件。耐心点。如果您的WAR文件很大,这可能需要几分钟时间。观察任务管理器,看看Tomcat正在使用多少CPU。如果使用90%或更多,则可能无法完成部署过程。
如果重新部署不起作用,请停止tomcat,删除WAR文件,在Web应用程序文件夹中放置一个新的WAR文件,重新启动Tomcat并等待部署过程完成。
