gradle spring hello word

在本教程中，我们将向您展示Gradle + Spring 4 MVC，Hello World示例（JSP视图），XML配置。

使用的技术：

Gradle 2.0
春天4.1.6.RELEASE
Eclipse 4.4
JDK 1.7
登入1.1.3
Boostrap 3

1.项目结构

下载项目源代码并查看项目文件夹结构：

2. Gradle构建

2.1查看build.gradle文件，这应该是不言自明的。

build.gradle


apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'eclipse-wtp'
apply plugin: 'jetty'
 
// JDK 7
sourceCompatibility = 1.7
targetCompatibility = 1.7
 
repositories {
    mavenLocal()
    mavenCentral()
}
 
dependencies {
	compile 'ch.qos.logback:logback-classic:1.1.3'
	compile 'org.springframework:spring-webmvc:4.1.6.RELEASE'
	compile 'javax.servlet:jstl:1.2'
}
 
// Embeded Jetty for testing
jettyRun{
	contextPath = "spring4"
	httpPort = 8080
}
 
jettyRunWar{
	contextPath = "spring4"
	httpPort = 8080
}
 
//For Eclipse IDE only
eclipse {
 
  wtp {
    component {
      
      //define context path, default to project folder name
      contextPath = 'spring4'
      
    }
    
  }
}

2.2为了使该项目支持Eclipse IDE，发出gradle eclipse ：

your-project$ gradle eclipse

3. Spring MVC

Spring MVC相关的东西。

3.1 Spring Controller – @Controller和@RequestMapping 。

WelcomeController.java


package com.mkyong.helloworld.web;
 
import java.util.Map;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
 
import com.mkyong.helloworld.service.HelloWorldService;
 
@Controller
public class WelcomeController {
 
	private final Logger logger = LoggerFactory.getLogger(WelcomeController.class);
	private final HelloWorldService helloWorldService;
 
	@Autowired
	public WelcomeController(HelloWorldService helloWorldService) {
		this.helloWorldService = helloWorldService;
	}
 
	@RequestMapping(value = "/", method = RequestMethod.GET)
	public String index(Map<String, Object> model) {
 
		logger.debug("index() is executed!");
 
		model.put("title", helloWorldService.getTitle(""));
		model.put("msg", helloWorldService.getDesc());
		
		return "index";
	}
 
	@RequestMapping(value = "/hello/{name:.+}", method = RequestMethod.GET)
	public ModelAndView hello(@PathVariable("name") String name) {
 
		logger.debug("hello() is executed - $name {}", name);
 
		ModelAndView model = new ModelAndView();
		model.setViewName("index");
		
		model.addObject("title", helloWorldService.getTitle(name));
		model.addObject("msg", helloWorldService.getDesc());
		
		return model;
 
	}
 
}

3.2生成消息的服务。

HelloWorldService.java


package com.mkyong.helloworld.service;
 
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Service;
import org.springframework.util.StringUtils;
 
@Service
public class HelloWorldService {
 
	private static final Logger logger = LoggerFactory.getLogger(HelloWorldService.class);
 
	public String getDesc() {
 
		logger.debug("getDesc() is executed!");
 
		return "Gradle + Spring MVC Hello World Example";
 
	}
 
	public String getTitle(String name) {
 
		logger.debug("getTitle() is executed! $name : {}", name);
 
		if(StringUtils.isEmpty(name)){
			return "Hello World";
		}else{
			return "Hello " + name;
		}
		
	}
 
}

3.3视图– JSP + JSTL +引导程序。一个简单的JSP页面来显示模型，并包含诸如CSS和JS之类的静态资源。

/WEB-INF/views/jsp/index.jsp


<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<link href="${bootstrapCss}" rel="stylesheet" />
<link href="${coreCss}" rel="stylesheet" />

<nav class="navbar navbar-inverse navbar-fixed-top">

<script src="${bootstrapJs}"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>

</html>

3.4日志记录–将所有日志发送到控制台。

logback.xml


<?xml version="1.0" encoding="UTF-8"?>
<configuration>
 
	<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
	  <layout class="ch.qos.logback.classic.PatternLayout">
 
		<Pattern>
		%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n
		</Pattern>
 
	  </layout>
	</appender>
 
	<logger name="org.springframework" level="debug" 
                additivity="false">
		<appender-ref ref="STDOUT" />
	</logger>
	
	<logger name="com.mkyong.helloworld" level="debug" 
                additivity="false">
		<appender-ref ref="STDOUT" />
	</logger>
	
	<root level="debug">
		<appender-ref ref="STDOUT" />
	</root>
 
</configuration>

4. Spring XML配置

Spring XML配置文件。

4.1 Spring根上下文。

spring-core-config.xml


<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="
        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 ">
 
	<context:component-scan base-package="com.mkyong.helloworld.service" />
 
</beans>

4.2 Spring Web或Servlet上下文。

spring-web-config.xml


<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="
        http://www.springframework.org/schema/beans     
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context.xsd ">
 
	<context:component-scan base-package="com.mkyong.helloworld.web" />
 
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
		<property name="prefix" value="/WEB-INF/views/jsp/" />
		<property name="suffix" value=".jsp" />
	</bean>
 
	<mvc:resources mapping="/resources/**" location="/resources/" />
	 
	<mvc:annotation-driven />
 
</beans>

4.3经典web.xml

web.xml


<web-app xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	version="2.5">
 
	<display-name>Gradle + Spring MVC Hello World + XML</display-name>
	<description>Spring MVC web application</description>
 
	<!-- For web context -->
	<servlet>
		<servlet-name>hello-dispatcher</servlet-name>
		<servlet-class>
                        org.springframework.web.servlet.DispatcherServlet
                </servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>/WEB-INF/spring-mvc-config.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
 
	<servlet-mapping>
		<servlet-name>hello-dispatcher</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
 
	<!-- For root context -->
	<listener>
		<listener-class>
                  org.springframework.web.context.ContextLoaderListener
                </listener-class>
	</listener>
 
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/spring-core-config.xml</param-value>
	</context-param>
 
</web-app>

5.演示

5.1 gradle.build文件定义为嵌入式Jetty容器。 gradle jettyRun启动项目。

Terminal


your-project$ gradle jettyRun
 
:compileJava
:processResources
:classes
:jettyRun
//...SLF4j logging
 
> Building 75% > :jettyRun > Running at http://localhost:8080/spring4

5.2 http：// localhost：8080 / spring4 /

5.3 http：// localhost：8080 / spring4 / hello / mkyong.com

6. WAR文件

要创建用于部署的WAR文件：

Terminal

your-project$ gradle war

将在project\build\libs文件夹中创建一个WAR文件。

${Project}\build\libs\spring-web-gradle-xml.war

下载源代码

下载它– spring4-mvc-gradle-xml.zip （61 KB）

Github链接– spring4-mvc-gradle-xml-hello-world.git
