(一)springmvc+spring+mybatis+maven框架搭建
(一)springmvc+spring+mybatis+maven框架搭建
1.说明
工作之余,为了学习点东西。先搭建个框架。
以后要往里面加东西,比如rabbitMQ、redis、shiro等。
也是为了自己学习做一个demo吧。
2.项目文件
介绍:
application.properties文件:一些数据库连接参数,以后redis、rabbitMQ参数也加在里面。
applicationContet.xml文件: spring配置文件
log4j.properties:日志文件
message_en.properties和messages_zh_CN.properties文件:国际化文件
mybatis-config.xml文件:mybatis配置文件
spring-mvc.xml文件:mvc配置文件
3.maven的pom.xml文件
文件里引入了很多jar包,大家可以根据自己需要加自己用到的jar。

5.springmvc.xml配置
<?xml version="1.0" encoding="UTF-8"?> <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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:p="http://www.springframework.org/schema/p" xmlns:util="http://www.springframework.org/schema/util" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:cache="http://www.springframework.org/schema/cache" 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/util http://www.springframework.org/schema/util/spring-util.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd "> <!-- 自动扫描注解,只扫描的Controller注解,其它注解的扫描交给spring去处理 --> <context:component-scan base-package="com.ln.web.controller"/> <mvc:annotation-driven></mvc:annotation-driven> <!-- 配置springmvc的视图解析器 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/jsp/" p:suffix=".jsp"> </bean> </beans>
6.mybatis-config.xml文件
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "classpath:schema/mybatis-3-config.dtd"> <configuration> <typeAliases> <package name="com.ln.web.model"/> <package name="com.ln.web.enums"/> </typeAliases> </configuration>
7.编写测试类,测试数据库连接。
新建test
TestBase接口定义,以后所有的测试类都实现此接口即可。
package com.ln.web.controller; import org.junit.runner.RunWith; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = { "classpath*:applicationContext.xml"}) public abstract class TestBase extends AbstractJUnit4SpringContextTests{ }
UserTes测试类。
package com.ln.web.controller; import static org.junit.Assert.assertNotNull; import java.sql.Connection; import java.util.List; import javax.annotation.Resource; import org.apache.ibatis.session.SqlSessionFactory; import org.junit.Test; import org.springframework.beans.factory.annotation.Autowired; import com.ln.web.model.User; import com.ln.web.service.UserService; public class UserTest extends TestBase { @Resource private UserService userService; @Autowired private SqlSessionFactory factory; /** * 测试数据库连接 */ @Test public void testConn() { Connection con = factory.openSession().getConnection(); assertNotNull("数据库连接失败!!!", con); } /** * 测试 */ @Test public void listTest() { List<User> list = userService.getList(); System.out.println(list.size()); } }
运行结果:
有问题自己在检查配置。
至于listTest()测试,我新建了userService、userServiceImpl.这里就不贴代码了,就是一个简单调用。
user实体类、userMapper和userMapper.xml文件都是通过Mybatic自动生成的。在pom.xml文件中加入了这个插件。
只要在配置两个文件:generatorConfig.properties和generatorConfig.xml
generatorConfig.properties文件 :
链接的数据库,用户名、密码根据自己项目改下。
包路径配置根据自己项目的包路径配置下。
# 数据库驱动jar 路径 drive.class.path=C\:\\Users\\Administrator\\.m2\\repository\\mysql\\mysql-connector-java\\5.1.30\\mysql-connector-java-5.1.30.jar # 数据库连接参数 jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/ssm?useUnicode=true&characterEncoding=utf-8 jdbc.username=simple jdbc.password=1234 # 包路径配置 model.package=com.ln.web.model dao.package=com.ln.web.dao xml.mapper.package=com.ln.web.dao target.project=src/main/java
generatorConfig.xml文件:
需要生成的表名,根据自己项目改下就可以了:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"> <!-- 配置Run As Maven build : Goals 参数 : mybatis-generator:generate -Dmybatis.generator.overwrite=true --> <!-- 配置 tableName,使用 Run As Maven build 生成 dao model 层 --> <generatorConfiguration> <!-- 配置文件路径 --> <properties url="${mybatis.generator.generatorConfig.properties}"/> <!--数据库驱动包路径 --> <classPathEntry location="${drive.class.path}"/> <context id="DB2Tables" targetRuntime="MyBatis3"> <!--关闭注释 --> <commentGenerator> <property name="suppressAllComments" value="http://www.mamicode.com/true"/> </commentGenerator> <!--数据库连接信息 --> <jdbcConnection driverClass="${jdbc.driver}" connectionURL="${jdbc.url}" userId="${jdbc.username}" password="${jdbc.password}"> </jdbcConnection> <!--生成的model 包路径 --> <javaModelGenerator targetPackage="${model.package}" targetProject="${target.project}"> <property name="enableSubPackages" value="http://www.mamicode.com/ture"/> <property name="trimStrings" value="http://www.mamicode.com/true"/> </javaModelGenerator> <!--生成xml mapper文件 路径 --> <sqlMapGenerator targetPackage="${xml.mapper.package}" targetProject="${target.project}"> <property name="enableSubPackages" value="http://www.mamicode.com/ture"/> </sqlMapGenerator> <!-- 生成的Dao接口 的包路径 --> <javaClientGenerator type="XMLMAPPER" targetPackage="${dao.package}" targetProject="${target.project}"> <property name="enableSubPackages" value="http://www.mamicode.com/ture"/> </javaClientGenerator> <!--对应数据库表名 --> <table tableName="user_table"></table> </context> </generatorConfiguration>
8.web.xml文件。
<?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" 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"> <!-- 加载spring容器 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value> classpath*:applicationContext.xml </param-value> </context-param> <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>UTF-8</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> <!-- 日志 --> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>classpath:log4j.properties</param-value> </context-param> <context-param> <param-name>log4jRefreshInterval</param-name> <param-value>60000</param-value> </context-param> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> <!-- 配置springmvc的dispatchServlet的处理类 --> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <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>dispatcher</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> </web-app>
注:
我的项目创建的时候不是web项目,要把项目转成web项目生成web.xml文件:
可以参考:http://www.cnblogs.com/kaige123/p/5866446.html
9.测试、启动项目,访问:
index.jsp:
<%@ page contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>用户登录界面</title> </head> <body> <form action="user/login.action" method="post" style="text-align: center; margin: 80px auto; width: 500px;"> <p>用户名:<input type="text" name="username" /></p> <p>密码:<input type="password" name="password" /></p> <input type="submit" value="http://www.mamicode.com/登录"/> </form> </body> </html>
userController:
package com.ln.web.controller; import java.util.List; import javax.annotation.Resource; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; import com.ln.web.model.User; import com.ln.web.service.UserService; @Controller @RequestMapping(value="http://www.mamicode.com/user") public class UserController { @Resource private UserService userService; @RequestMapping(value="http://www.mamicode.com/login") public ModelAndView login(User user){ ModelAndView mav=new ModelAndView(); mav.setViewName("success"); return mav; } }
运行结果:
(一)springmvc+spring+mybatis+maven框架搭建
