Konfigurieren Sie statische Ressourcen in Spring MVC

Das Zweck des Unterlagen
Maven Project erstellen
Maven & web.xml konfigurieren
Spring MVC konfigurieren
Spring Controllers
Static Resource & Views
Die Applikation laufen

1. Das Zweck des Unterlagen

Der Unterlagen wird nach der Quelle von ... geschrieben

Eclipse 4.6 (NEON)
Spring 4 MVC

Im Unterlagen leite ich Sie bei der Konfiguration der static Data Sources im Spring MVC an, Die static Data sources sind oft die Foto-File, die css File und javascript,...

Spring MVC erlaubt Sie die Abbildung zwischen einen URL mit einem bestimmten Position von Data Source. Sie können das folgende Beispiel sehen

2. Maven Project erstellen

File/New/Other..

Geben Sie ein

Group ID: org.o7planning
Artifact ID: SpringMVCStaticResource
Package: org.o7planning.tutorial.springmvcresource

Das Projekt wird erstellt

Do not worry with the error message when Project has been created. The reason is that you have not declared Servlet library.

Beachten Sie:
Eclipse erstellt das Projekt Maven, dessen Struktur falsch sein kann. Sie sollen prüfen und verändern

Stellen Sie sicher, dass Ihr Projekt Java >=6 benutzt

Project properties:

3. Maven & web.xml konfigurieren

web.xml durch die Benutzung von Web App >= 3 benutzen .

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"

    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    id="WebApp_ID" version="3.0">
   
    <display-name>SpringMVCResource</display-name>
   
</web-app>

4. Spring MVC konfigurieren

SpringWebAppInitializer.java

package org.o7planning.springmvcresource.config;

import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRegistration;

import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.servlet.DispatcherServlet;

public class SpringWebAppInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        AnnotationConfigWebApplicationContext appContext = new AnnotationConfigWebApplicationContext();
        appContext.register(ApplicationContextConfig.class);

        ServletRegistration.Dynamic dispatcher = servletContext.addServlet("SpringDispatcher",
                new DispatcherServlet(appContext));
        dispatcher.setLoadOnStartup(1);
        dispatcher.addMapping("/");
    }

}

ApplicationContextConfig.java

package org.o7planning.springmvcresource.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

@Configuration

@ComponentScan("org.o7planning.springmvcresource.*")
public class ApplicationContextConfig {

    @Bean(name = "viewResolver")
    public InternalResourceViewResolver getViewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();

        viewResolver.setPrefix("/WEB-INF/pages/");
        viewResolver.setSuffix(".jsp");

        return viewResolver;
    }
 
}

WebMvcConfig.java

package org.o7planning.springmvcresource.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;


@Configuration
@EnableWebMvc
public class WebMvcConfig extends WebMvcConfigurerAdapter {

   // Static Resource Config
   @Override
   public void addResourceHandlers(ResourceHandlerRegistry registry) {
   
       // Css resource.
       registry.addResourceHandler("/styles/**") //
                 .addResourceLocations("/WEB-INF/resources/css/").setCachePeriod(31556926);
       
   }

   
   @Override
   public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
       configurer.enable();
   }

}

Achtung

Die Konfiguration von Static Resource:

// Css resource.
registry.addResourceHandler("/styles/**") //
          .addResourceLocations("/WEB-INF/resources/css/");

5. Spring Controllers

MyController.java

package org.o7planning.springmvcresource.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class MainController {

    @RequestMapping(value = "/staticResourceTest")
    public String staticResource(Model model) {
        return "staticResourceTest";
    }
    
}

6. Static Resource & Views

Static Resource

scripts/common.js

function sayHello()  {    
  alert("Hello from JavaScript");
}

/WEB-INF/resource/css/commons.css

.button {
  font-size: 20px;
  background: #ccc;
}

.red-text {
  color: red;
  font-size: 30px;
}

.green-text {
  color: green;
  font-size: 20px;
}

Views

staticResourceTest.jsp

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">

<title>Spring MVC Resource example</title>


<script type="text/javascript"
    src="${pageContext.request.contextPath}/scripts/common.js"></script>


<link rel="stylesheet" type="text/css"
    href="${pageContext.request.contextPath}/styles/common.css">

</head>
<body>

<pre>
Config: /styles/** ==> /WEB-INF/resources/css/
----------------------------------------------
        /styles/common.css ==> /WEB-INF/resources/css/common.css
        /styles/path1/abc.css ==> /WEB-INF/resources/css/path1/abc.css
        /styles/path1/path2/abc.css ==> /WEB-INF/resources/css/path1/path2/abc.css
</pre>


    <div class="red-text">Red text</div>
    <br>
    <div class="green-text">Green text</div>
    <br>

    <input type="button" class="button" onclick="sayHello();"
        value="Click me!">

</body>
</html>

index.jsp

<html>
<body>
 
 <a href="staticResourceTest">staticResourceTest</a>
 
</body>
</html>

7. Die Applikation laufen

Zum ersten Mal sollen Sie vor dem Laufen der Applikation das ganze Projekt bauen ( build ).

Klicken Sie mit der rechten Maustaste auf dem Projekt und wählen Sie

Konfigurieren zu laufen

Geben Sie ein

Name: Run SpringMVCResource
Base directory: ${workspace_loc:/SpringMVCResource}
Goals: tomcat7:run

Klicken Sie auf Run

Static Resource Test:

http://localhost:8080/SpringMVCResource/scripts/common.js

http://localhost:8080/SpringMVCResource/styles/common.css

http://localhost:8080/SpringMVCResource/staticResourceTest
