Spring配置

一、添加Spring依赖

<dependencyManagement>
		<dependencies>
			<!-- 使用spring的BOM管理依赖 -->
			<dependency>
				<groupId>org.springframework</groupId>
				<artifactId>spring-framework-bom</artifactId>
				<version>4.2.6.RELEASE</version>
				<type>pom</type>
				<scope>import</scope>
			</dependency>
		</dependencies>
	</dependencyManagement>

	<dependencies>
		<!-- spring配置开始 -->
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-context</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-web</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-webmvc</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-core</artifactId>
			<exclusions>
				<exclusion>
					<groupId>commons-logging</groupId>
					<artifactId>commons-logging</artifactId>
				</exclusion>
			</exclusions>
		</dependency>
		<!-- spring配置结束 -->
	</dependencies>

二、配置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" xmlns:web="http://java.sun.com/xml/ns/javaee"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	id="WebApp_ID" version="2.5">

	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath*:META-INF/dispatcher.xml</param-value>
	</context-param>
	<servlet>
		<servlet-name>dispatcher</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value></param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>dispatcher</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<filter>
		<filter-name>encodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>utf8</param-value>
		</init-param>
		<init-param>
			<param-name>forceEncoding</param-name>
			<param-value>true</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>encodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
	<servlet-mapping>
		<servlet-name>default</servlet-name>
		<url-pattern>*.html</url-pattern>
	</servlet-mapping>
	<welcome-file-list>
		<welcome-file>index.html</welcome-file>
	</welcome-file-list>
</web-app>

　　

三、添加dispatcher.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.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">

	<!-- 加入下面这两个配置才能支持注解功能 -->
	<bean id="handlerMapping" class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
	<bean id="handlerAdapter" class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

	<!-- 本工程拦截器 -->
	<mvc:interceptors>
		<bean class="org.springframework.web.servlet.mvc.WebContentInterceptor">
			<property name="cacheSeconds" value="0" />
			<property name="useExpiresHeader" value="true" />
			<property name="useCacheControlHeader" value="true" />
			<property name="useCacheControlNoStore" value="true" />
			<property name="alwaysUseFullPath" value="true" />
		</bean>
	</mvc:interceptors> 
	
	<!-- 扫描包，如果用扫描则不用再写 <context:annotation-config /> -->
	<context:component-scan base-package="com.alan.controller" />
	<context:component-scan base-package="com.alan.service.impl" />
	<context:component-scan base-package="com.alan.dao.impl" />

</beans>

　　

四、添加controller/service/dao等类

TestDaoImpl.java

package com.alan.dao.impl;

import org.springframework.stereotype.Repository;

import com.alan.dao.TestDao;

@Repository("testDao")
public class TestDaoImpl implements TestDao {

	@Override
	public String test() {
		return "../index.html";
	}

}

　　

TestServiceImpl.java

package com.alan.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.alan.dao.TestDao;
import com.alan.service.TestService;

@Service("testService")
public class TestServiceImpl implements TestService {

	@Autowired
	private TestDao testDao;
	
	@Override
	public String test() {
		return testDao.test();
	}
	
}

　　

TestController.java

package com.alan.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.alan.service.TestService;


@RestController
@RequestMapping("/alan")
public class TestController {
		
	@Autowired
	private TestService testService;
	
	@RequestMapping("/test")
	public String test(){
		return testService.test();
	}
	
}
