问题:我无法通过我的Spring Boot web MVC应用程序在WEB-INF/jsp
下看到我的视图。Spring boot MVC:找不到JSP
我做了什么:
这是我的JSP:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<ul>
<%[email protected] id="users" type="java.util.List"--%>
<c:forEach items="${utenti}" var="utente">
<li>
<c:out value="${utente.getUsername()}"/>
</li>
</c:forEach>
</ul>
</body>
</html>
这是我的控制器:
@Controller
public class UtenteController {
@Autowired
private UtenteService utenteService;
@RequestMapping("/lista_utenti")
public ModelAndView getListaUtentiView(){
ModelMap model = new ModelMap();
model.addAttribute("utenti", this.utenteService.getListaUtenti());
return new ModelAndView("lista_utenti", model);
}
}
这是我的application.properties:
# MVC
spring.view.prefix=/WEB-INF/jsp/
spring.view.suffix=.jsp
#Postgres config
spring.datasource.driverClassName=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/DB_Test
spring.datasource.username=postgres
spring.datasource.password=postgres
和,至少,我的主要应用:
@Configuration
@EnableAutoConfiguration
@ComponentScan
public class SpringWebApplication extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(SpringWebApplication.class, args);
}
@Override
protected final SpringApplicationBuilder configure(final SpringApplicationBuilder application) {
return application.sources(SpringWebApplication.class);
}
}
如果我去http://localhost:8080/lista_utenti
我得到的是:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
No message available
我在做什么错?
貌似服务器不能够找到控制器(不像您提到的JSP文件)。盯着服务器时是否有任何异常? – kranthi117 2015-01-15 15:24:05
不,它实际上开始罚款..它也显示在控制台上: “映射”{[/ lista_utenti],methods = []“... – abierto 2015-01-15 15:25:50
您是使用嵌入式容器,还是部署战争文件到单独的servlet容器?假设你使用的是SpringBootServletInitializer,我猜测它是后者,但它确实有用。另外,你是否检查过JSP是否打包在你的jar或war文件中的预期位置? – 2015-01-15 16:09:16
