[英]STS mapping controller to view
I am studying STS 我正在学习STS
I am started starter project with jpa,web 我从jpa,web开始了启动项目
my code SpringProjectApplication.java is 我的代码SpringProjectApplication.java是
package com.example;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SpringProjectApplication {
public static void main(String[] args) {
SpringApplication.run(SpringProjectApplication.class, args);
}
}
and my Homecontroller.java is 而我的Homecontroller.java是
package com.example;
import java.util.Locale;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
/**
* Handles requests for the application home page.
*/
@RestController
public class HomeController {
/**
* Simply selects the home view to render by returning its name.
*/
@RequestMapping("/")
public String helloWorld(Locale locale, Model model) {
return "home";
}
@RequestMapping(value = "/login", method = RequestMethod.POST)
public String verifyLogin(Locale locale, Model model) {
return "login";
}
@RequestMapping(value = "/SignUp", method = RequestMethod.GET)
public String SignUp(Locale locale, Model model) {
return "SignUp";
}
}
and servlet-context.xml is 和servlet-context.xml是
<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:beans="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure -->
<!-- Enables the Spring MVC @Controller programming model -->
<annotation-driven />
<!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory -->
<resources mapping="/resources/**" location="/resources/" />
<!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory -->
<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<beans:property name="prefix" value="/WEB-INF/views/" />
<beans:property name="suffix" value=".jsp" />
</beans:bean>
<context:component-scan base-package="come.example" />
and home.jsp is 和home.jsp是
overall structure is 整体结构是
I think if homecontroller is mapped with home.jsp 我认为homecontroller是否与home.jsp映射
localhost:8080/ show "hello world" 本地主机:8080 /显示“你好,世界”
but result is "home" 但结果是“家”
so not mapped 所以没有映射
I want to solve it. 我想解决。
help me. 帮我。
If you want to render a view -> meaning you want to show home.jsp page you need to change your class annotation from @RestController to @Controller. 如果要渲染视图->表示要显示home.jsp页面,则需要将类注释从@RestController更改为@Controller。 With @RestController u return JSON or XML, also uncomment internalViewResolver Bean in your servlet-context.xml. 使用@RestController,您可以返回JSON或XML,还可以在servlet-context.xml中取消注释internalViewResolver Bean。
