mybatis 与Spring 的整合.
1.导入Spring 和Springmvc的包
pom
<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>cn.mjorcen.prot</groupId> <artifactId>prot</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <name /> <description /> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>3.2.0.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>3.2.0.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>3.2.0.RELEASE</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.1.1</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.1.1</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.21</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>0.2.9</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.7.1</version> </dependency> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.11</version> </dependency> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.2.2</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>3.0-alpha-1</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.1.26</version> </dependency> </dependencies> <build> <plugins> <plugin> <artifactId>maven-war-plugin</artifactId> </plugin> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.6</source> <target>1.6</target> </configuration> </plugin> </plugins> </build> </project>
2. 添加spring-mvc.xml 文件
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" 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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <!-- 自动扫描controller包下的所有类，使其认为spring mvc的控制器 --> <context:component-scan base-package="com.sd" /> <!-- 避免IE执行AJAX时,返回JSON出现下载文件 --> <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> </list> </property> </bean> <!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <list> <ref bean="mappingJacksonHttpMessageConverter" /><!-- json转换器 --> </list> </property> </bean> <!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/" p:suffix=".jsp" /> <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> </beans>
3.添加spring-application.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:aop="http://www.springframework.org/schema/aop" xmlns:c="http://www.springframework.org/schema/c" xmlns:cache="http://www.springframework.org/schema/cache" xmlns:context="http://www.springframework.org/schema/context" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:lang="http://www.springframework.org/schema/lang" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:p="http://www.springframework.org/schema/p" xmlns:task="http://www.springframework.org/schema/task" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee.xsd http://www.springframework.org/schema/lang http://www.springframework.org/schema/lang/spring-lang.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd"> <!-- 自动扫描dao和service包(自动注入) --> <context:component-scan base-package="com.sd" /> <aop:aspectj-autoproxy /> <!-- <import resource="spring-mybatis.xml" /> --> </beans>
4 . 修改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/web-app_2_5.xsd" xsi:schemaLocation="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>mybatis</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-*.xml</param-value> </context-param> <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> <listener> <description>spring监听器</description> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <servlet> <description>spring mvc servlet</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-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMvc</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> <session-config> <session-timeout>15</session-timeout> </session-config> </web-app>
5. controller 如下
1 package com.sd.test.controller; 2 3 import java.io.IOException; 4 5 import javax.annotation.Resource; 6 import javax.servlet.http.HttpServletRequest; 7 import javax.servlet.http.HttpServletResponse; 8 9 import org.springframework.stereotype.Controller; 10 import org.springframework.web.bind.annotation.RequestMapping; 11 12 import com.sd.test.model.TTest; 13 import com.sd.test.service.TestService; 14 15 @Controller 16 @RequestMapping("/test") 17 public class TestController { 18 @Resource 19 private TestService testService; 20 21 @RequestMapping("selectOne") 22 public void findById(HttpServletRequest request, 23 HttpServletResponse response) throws IOException { 24 String id = request.getParameter("id"); 25 Object obj = this.testService.selectOne(Integer.parseInt(id)); 26 response.getWriter().print(obj); 27 } 28 29 @RequestMapping("save") 30 public void save(HttpServletRequest request, HttpServletResponse response) { 31 String name = request.getParameter("name"); 32 TTest t = new TTest(); 33 t.setUsername(name); 34 this.testService.save(t); 35 36 } 37 38 @RequestMapping("tsave") 39 public void tsave(HttpServletRequest request, HttpServletResponse response) { 40 String name = request.getParameter("name"); 41 TTest t = new TTest(); 42 t.setUsername(name); 43 int i = (Integer) this.testService.put(t); 44 System.out.println(i); 45 } 46 47 }
serviceImpl 如下:
package com.sd.test.service.impl; import javax.annotation.Resource; import org.springframework.stereotype.Service; import com.sd.test.dao.TTestMapper; import com.sd.test.model.TTest; import com.sd.test.service.TestService; @Service public class TestServiceImpl implements TestService { // @Resource // private TTestMapper mapper; @Override public void save(Object obj) { // int i = this.mapper.insert((TTest) obj); // System.out.println("save = " + i); System.out.println("save"); } @Override public Object selectOne(Object obj) { System.out.println("selectOne"); TTest tt = null; // TTest tt = this.mapper.selectByPrimaryKey(Integer.parseInt(obj // .toString())); return tt; } @Override public Object put(Object obj) { System.out.println("put"); // return this.mapper.insert((TTest) obj); return null; } }
启动项目.访问http://localhost:8080/prot/test/selectOne.do?id=1
控制台:
selectOne
到此为止, spring mvc 部署成功.
