关于spring+springmvc+mybatis+maven的框架整合实例

2017-01-11 15:48 639 查看
         最近在学习基于maven环境的ssm框架整合,小弟不才,学的不好,然后在百度上搜了一下ssm框架整合的实例,然后按照上面一片点赞很高的进行ctrl+C,ctrl+V,然后再改自己的参数,但是改了后,不是这错,就是那不对。最后让项目经理找原因,项目经理说:配的乱七八糟的,  然后给了我springmvc的框架教程,有需要的在这里http://www.yiibai.com/spring/spring_web_mvc_framework.html,还有一个是搭建简单的springmvc框架教程http://blog.csdn.net/aitcax/article/details/41543829,最后在自己
学习后,总于配置成功。

     下面小弟将把自己的配置一步步贴出来,供大家参考。

   第一步:创建基于maven的项目:

 



其中的pom.xml里的配置文件内容根据各自的需要加入就行,这里我不再贴出。

 

第二步;在resources里咱们的配置文件了


这是里面所有的配置文件

先写第一个:sqlMapConfig.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<typeAliases>
<typeAlias alias="User" type="com.jmt.pojo.User" />
<!-- 	<typeAlias alias="Role" type="com.jmt.pojo.Role" />
<typeAlias alias="Menu" type="com.jmt.pojo.Menu" />
<typeAlias alias="Office" type="com.jmt.pojo.Office" /> -->
<!-- <typeAlias alias="User" type="com.jmt.pojo.SysUser" />
<typeAlias alias="User" type="com.jmt.pojo.SysUser" /> -->
</typeAliases>
<mappers>
<mapper resource="com/jmt/mapping/loginDaoMapper.xml" />
<!-- <mapper resource="com/jmt/mapping/SysRoleMapper.xml" />
<mapper resource="com/jmt/mapping/SysMenuMapper.xml" />
<mapper resource="com/jmt/mapping/SysOfficeMapper.xml" />
<mapper resource="com/jmt/mapping/SysRoleOfficeMapper.xml" />
<mapper resource="com/jmt/mapping/SysUserRoleMapper.xml" />
<mapper resource="com/jmt/mapping/SysRoleMenuMapper.xml" /> -->
</mappers>
</configuration>

  第二步就是编写咱们的applicationContext-dao.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"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 配置整合mybatis过程 -->
<!-- 1.配置数据库相关参数properties的属性:${url} -->
<context:property-placeholder location="classpath:jdbc.properties" />

<!-- 2.数据库连接池 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="${jdbc.driver}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<!-- 初始化连接大小 -->
<property name="initialSize" value="${initialSize}"></property>
<!-- 连接池最大数量 -->
<property name="maxActive" value="${maxActive}"></property>
<!-- 连接池最大空闲 -->
<property name="maxIdle" value="${maxIdle}"></property>
<!-- 连接池最小空闲 -->
<property name="minIdle" value="${minIdle}"></property>
<!-- 获取连接最大等待时间 -->
<property name="maxWait" value="${maxWait}"></property>
</bean>
<!-- 3.配置SqlSessionFactory对象 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 注入数据库连接池 -->
<property name="dataSource" ref="dataSource" />
<!-- 配置MyBaties全局配置文件:sqlMapConfig.xml-->
<property name="configLocation" value="classpath:sqlMapConfig.xml" />
<!-- 扫描entity包 使用别名 -->
<property name="typeAliasesPackage" value="com.jmt.pojo" />

</bean>

<!-- 4.配置扫描Dao接口包,动态实现Dao接口,注入到spring容器中 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 注入sqlSessionFactory -->
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />

<!-- 给出需要扫描Dao接口包 -->
<property name="basePackage" value="com.jmt.dao" />
</bean>
</beans>


第三部编写咱们的applicationContext-service.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:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- 扫描service包下所有使用注解的类型 -->
<context:component-scan base-package="com.jmt.service" />

</beans>


第四步:编写咱们的applicationContext-transaction.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:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- 配置事务管理器 -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!-- 注入数据库连接池 -->
<property name="dataSource" ref="dataSource" />
</bean>

<!-- 配置基于注解的声明式事务 -->
<tx:annotation-driven transaction-manager="transactionManager" />
</beans>


这些都编辑好以后,   编辑咱们的web.xml

 

<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">

<!-- springmvc整合 -->

<!-- spring MVC的核心就是DispatcherServlet,使用springMVC的第一步就是将下面的servlet放入web.xml
servlet-name属性非常重要,默认情况下,DispatchServlet会加载这个名字-servlet.xml的文件,如下,就会加载
dispather-servlet.xml,也是在WEN-INF目录下。
-->
<!--配置监听器-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext-*.xml</param-value>
</context-param>
<servlet>
<servlet-name>Spring-SpringMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:Spring-SpringMVC.xml</param-value>
</init-param>
<!--随sevlet的启动加载-->
<load-on-startup>1</load-on-startup>

</servlet>
<!-- 设置dispatchservlet的匹配模式,通过把dispatchservlet映射到/,默认servlet会处理所有的请求,包括静态资源 -->
<servlet-mapping>
<servlet-name>Spring-SpringMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!-- 字符集过滤器 -->
<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>

<display-name>ssmDemo</display-name>
<welcome-file-list>

<welcome-file>index.jsp</welcome-file>

</welcome-file-list>
</web-app>


最后一步就是编写咱们的Spring-SpringMVC.xml

 

<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:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.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" default-lazy-init="true">
<!-- 通过mvc:resources设置静态资源,这样servlet就会处理这些静态资源,而不通过控制器 -->
<!-- 设置不过滤内容,比如:css,jquery,img 等资源文件 -->
<mvc:resources location="/*.html" mapping="/**.html" />
<mvc:resources location="/css/*" mapping="/css/**" />
<mvc:resources location="/js/*" mapping="/js/**" />
<mvc:resources location="/images/*" mapping="/images/**" />
<!-- 添加注解驱动 -->
<mvc:annotation-driven />
<!-- 默认扫描的包路径 -->
<context:component-scan base-package="com.jmt" />
<!-- mvc:view-controller可以在不需要Controller处理request的情况,转向到设置的View -->
<!-- 像下面这样设置,如果请求为/,则不通过controller,而直接解析为/index.jsp -->
<mvc:view-controller path="/" view-name="index" />

<!-- 总错误处理 -->
<bean id="exceptionResolver"
class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
<property name="defaultErrorView">
<value>/jsp/error/admin-error.jsp</value>
</property>
<property name="defaultStatusCode">
<value>500</value>
</property>
<property name="warnLogCategory">
<value>org.springframework.web.servlet.handler.SimpleMappingExceptionResolver
</value>
</property>
</bean>

<bean class="org.springframework.web.servlet.view.UrlBasedViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView"></property>
<!-- 配置jsp路径前缀 -->
<property name="prefix" value="/jsp/"></property>
<!-- 配置URl后缀 -->
<property name="suffix" value=".jsp"></property>
</bean>
</beans>


这些都配置好以后,就可以添加到Tomcat里运行了。   写的太过简单,大家包涵就行。
