我正在尝试使用Spring 4构建一个小的Hello World WebApp原型,而没有任何xml文件配置。
比起我用tomcat 7,这是我的pom:
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>4.0.6.RELEASE</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
</dependency>
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>javax.servlet.jsp-api</artifactId>
<version>2.3.1</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
</dependencies>
比我有这个配置类:
@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "it.spring4.configuration")
public class HelloWorldConfiguration {
@Bean
public ViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new
InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
}
和网络初始化程序类:
public class HelloWorldInitializer extends
AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] { HelloWorldConfiguration.class };
}
@Override
protected Class<?>[] getServletConfigClasses() {
return null;
}
@Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
}
控制器:
@Controller
@RequestMapping("/")
public class HelloWorldController {
@RequestMapping(value = "/hello", method = RequestMethod.GET)
public String sayHello(ModelMap model) {
model.addAttribute("greeting", "Hello World from Spring 4 MVC");
return "welcome";
}
@RequestMapping(value = "/helloagain", method = RequestMethod.GET)
public String sayHelloAgain(ModelMap model) {
model.addAttribute("greeting", "Hello World Again, from Spring 4 MVC");
return "welcome";
}
}
并在WEB-INF下包含welcome.jsp的文件夹视图:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!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=ISO-8859-1">
<title>HelloWorld page</title>
</head>
<body>
Greeting : ${greeting}
</body>
</html>
这是在here下找到的示例,无法正常工作。我尝试了其他类似的示例,但没有人工作..您能解释一下我错了吗?
抱歉,错误是:
HTTP Status 404 – Not Found
Type Status Report
Message /Spring4FullAnnotation/
Description The origin server did not find a current representation for the
target resource or is not willing to disclose that one exists.
该死的。我不下载示例,我只是在日食中复制代码...我没有maven项目,我仅使用maven来解决依赖关系(我在之后创建了一个动态Web项目配置->转换为maven项目),通常我会在服务器上运行它。我已经用Spring4建立了许多如上所述的项目,它们可以正常运行。
我不知道为什么我不能启动它。代码很简单,并且功能不能依赖于Maven配置。
谢谢
