SpringMVC配置
导言
这篇文章应该放在最前面的,但是由于本人之前没用过mybatis所以,把mybatis整合提前。但是至少步骤变化而已,对于mvc的配置一样不影响。名字叫做特别篇````
一、jar包的引入
在jia上面有注释,除开标注mybatis的,其他包均为mvc包。你会发现这个神奇的mvc包,已经加载了所有的你需要的spring包。
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.ycy.springmvc</groupId> <artifactId>springmvc</artifactId> <packaging>war</packaging> <version>1.0-springmvc</version> <url>http://maven.apache.org</url> <build> <plugins> <!--=================generator-mybatis插件===========================--> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.2</version> <configuration> <!--此为generator配置文件路径--> <configurationFile>src/test/resources/generatorConfig.xml</configurationFile> <verbose>true</verbose> <overwrite>true</overwrite> </configuration> <executions> <execution> <id>Generate MyBatis Artifacts</id> <goals> <goal>generate</goal> </goals> </execution> </executions> <dependencies> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.2</version> </dependency> </dependencies> </plugin> </plugins> </build> <dependencies> <!--maven-resources-plugin配置resources文件位置(不建议)--> <!-- <dependency> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-resources-plugin</artifactId> <version>2.4.3</version> </dependency>--> <!--junit测试jar--> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> <!--==========================mysql数据库驱动配置==============================--> <dependency> <groupId>Mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.31</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.15</version> </dependency> <!--==========================spring配置======================================--> <!--注解、注入实体--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.2.0.RELEASE</version> </dependency> <!--事务管理--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.2.0.RELEASE</version> </dependency> <!--junit测试--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>4.2.0.RELEASE</version> </dependency> <!--事务管理--> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.8.0</version> </dependency> <!--==========================mybatis配置=========================================--> <!--mybatis驱动包--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.3.0</version> </dependency> <!--mybatis-spring结核驱动包--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.3</version> </dependency> <!--==========================httpservlet=========================================--> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>2.1</version> <scope>provided</scope> </dependency> <!--================json转换3人组文件上传(MappingJackson2HttpMessageConverter)==========--> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>2.6.1</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.6.1</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId> <version>2.6.1</version> </dependency> <!--==========================文件上传=========================================--> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.1</version> </dependency> </dependencies> </project>二、项目结构
三、配置spring-mvc文件
注意点:扫描包为主要的,我也看别人经验,实在扫描不到就加一个inclu-filter,spring-mvc.xml文件如下了
<?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:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"> <!-- 自动扫描controller包下的所有类,使其认为spring mvc的控制器(经验:加上include-filter) --> <context:component-scan base-package="com.ycy.controller"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- 对模型视图名称的解析,即在模型视图名称添加前后缀 --> <!-- 视图解析器也可以用标签:p:prefix="/" p:suffix=".jsp" --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/"/> <property name="suffix" value=".jsp"/> </bean> <!-- 对controller的请求实体转换为JSon(MappingJackson2HttpMessageConverter为spring4里面包) --> <mvc:annotation-driven> <mvc:message-converters register-defaults="true"> <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> <property name="prettyPrint" value="true"/> <property name="supportedMediaTypes"> <list> <value>application/json</value> <value>application/xml</value> <value>text/json</value> <value>text/html;charset=UTF-8</value> </list> </property> </bean> </mvc:message-converters> </mvc:annotation-driven> <!-- 对模型视图名称的解析,即在模型视图名称添加前后缀 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="defaultEncoding"> <value>UTF-8</value> </property> <property name="maxUploadSize"> <value>32505856</value><!-- 上传文件大小限制为31M,31*1024*1024 --> </property> <property name="maxInMemorySize"> <value>4096</value> </property> </bean> <!-- 配置拦截器(拦截所有请求) --> <!-- <mvc:interceptors> <mvc:interceptor> <mvc:mapping path="/**" /> <bean class="com.ycy.suport.controller.OperateInterceptor"></bean> </mvc:interceptor> </mvc:interceptors> --> </beans>
四、spring.xml的配置applicationContext.xml
<?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:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:aop="http://www.springframework.org/schema/aop" 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 http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> <!--配置文件properties--> <context:property-placeholder location="classpath:config/development.properties" /> <!-- 支持标注 --> <context:annotation-config /> <context:component-scan base-package="com.ycy"> <context:include-filter type="aspectj" expression="com.ycy.*" /> </context:component-scan> </beans>
五、web.xml的配置
<?xml version="1.0" encoding="UTF-8"?> <web-app version="3.0" 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_3_0.xsd" metadata-complete="false"> <display-name>springmvc</display-name> <!--===============加载spring容器配置文件1================ --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:spring/applicationContext.xml,classpath*:spring/spring-mybatis.xml</param-value> </context-param> <!--===============字符集过滤器2========================== --> <filter> <description>字符集过滤器</description> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <description>字符集编码</description> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- ===========spring容器监听==================== --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- ===========防止spring内存溢出监听器3==================== --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> <!--==========spring mvc servlet============================ --> <servlet> <description>spring mvc DispatcherServlet</description> <servlet-name>springMvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <description>spring mvc 配置文件</description> <param-name>contextConfigLocation</param-name> <param-value>classpath*:spring/spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMvc</servlet-name> <url-pattern>/*</url-pattern> <!-- <url-pattern>*.do</url-pattern>--> </servlet-mapping> <!--==========系统默认首页========================================= --> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> <!-- 配置session超时时间,单位分钟 --> <session-config> <session-timeout>15</session-timeout> </session-config> </web-app>
六、controller的编写
UserController.java
package com.ycy.controller; import com.ycy.model.UserAccount; import com.ycy.service.Userservice; 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.ResponseBody; import org.springframework.web.context.support.HttpRequestHandlerServlet; import javax.servlet.http.HttpServletRequest; /** * Created by Administrator on 2015/8/15 0015. */ @Controller @RequestMapping("/user") public class UserController { @Autowired private Userservice userService; @ResponseBody @RequestMapping("/getuser/{id}") public UserAccount getUserByUserId(@PathVariable String id, HttpServletRequest request ){ UserAccount u = userService.getUserAccountById(new Long(id)); request.setAttribute("user", u); return u; } }<span style="color:#3366ff;font-weight: bold;"> </span>七、测试结果

此文为本人初次编写博客,请多多包涵。很多拙劣之处多多指正。我也是看了网络一些的配置,还有根据项目中实际运用为前提编写此博客。本次编写时间2015-8-16 23:04:47,我在博客上和视频上都没有最新的mvc整合,为他人种树吧。如果有疑问请垂询我的qq:48599355 或者加一个群吧,反正只要我一个人,qq群号:78275755
如果你看到这篇文章在2年以后,请移步吧, 估计新的东西早就替代我啦····嘎嘎
