SSMA（SSM）的配置

SSMA

SpringMvc +Spring +Mybatis+Ajax=SSMA（基于maven）

1.springmvc

    1.1 springmvc核心配置jar包        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-webmvc</artifactId>            <version>4.2.0.RELEASE</version>        </dependency>            <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-jdbc</artifactId>            <version>4.2.0.RELEASE</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-aop</artifactId>            <version>4.2.0.RELEASE</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-tx</artifactId>            <version>4.2.0.RELEASE</version>        </dependency>        <dependency>            <groupId>aopalliance</groupId>            <artifactId>aopalliance</artifactId>            <version>1.0</version>        </dependency>        <dependency>            <groupId>org.apache.geronimo.bundles</groupId>            <artifactId>aspectjweaver</artifactId>            <version>1.6.8_2</version>        </dependency>        当配置完后，maven会自动配置其他所依赖的jar包    1.2 springmvc的核心配置文件        首先在web.xml文件中配置DispatcherServlet  <!-- 配置DispatcherServlet -->    <servlet>        <servlet-name>mymvc</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    <!-- 配置DispatcherServlet -->    <servlet>        <servlet-name>mymvc</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        <!-- 自定义springmvc配置文件名 --><init-param>    <param-name>contextConfigLocation</param-name>      <param-value>/WEB-INF/springmvc.xml</param-value>        </init-param>           <!-- 在服务器启动时就初始化(必须是大于0的值)-->        <load-on-startup>1</load-on-startup>    </servlet><!-- 拦截所有请求 --><servlet-mapping>        <servlet-name>mymvc</servlet-name>        <url-pattern>/</url-pattern>    </servlet-mapping>  其次在web.xml同级目录下创建一个xml文件(填入下方的代码)，命名规则是web.xml中的标签<servlet-name>中填写的值加“-Servlet”,默认这里应该命名为“mymvc-Servlet.xml”，但是我自定义了命名，所以应该是“springmvc.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:p="http://www.springframework.org/schema/p"    xmlns:context="http://www.springframework.org/schema/context"    xmlns:tx="http://www.springframework.org/schema/tx"    xmlns:aop="http://www.springframework.org/schema/aop"    xmlns:mvc="http://www.springframework.org/schema/mvc"    xsi:schemaLocation="    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd    http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd    ">    <!-- 类扫描，springmvc只扫描控制层 -->    <context:component-scan base-package="ssam"></context:component-scan>    <!-- 类扫描，springmvc只扫描控制层 -->    <context:component-scan base-package="ssam.controller">        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/>        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Repository"/>    </context:component-scan></beans>    1.2 配置支持restful风格的url               Web.xml中添加            <!-- 配置过滤器，请求method支持 put和delete必须添加过滤器,注意要在请求中要有_mehtod-->    <filter>        <filter-name>coding</filter-name>    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</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>coding</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>    1.3 配置字符拦截器Web.xml中添加        <!-- 配置拦截器设置字符集 -->    <filter>        <filter-name>charsetFilter</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>charsetFilter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>

2.spring

2.1 创建spring配置文件    在根目录下创建spirng.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:p="http://www.springframework.org/schema/p"    xmlns:context="http://www.springframework.org/schema/context"    xmlns:tx="http://www.springframework.org/schema/tx"    xmlns:aop="http://www.springframework.org/schema/aop"    xsi:schemaLocation="    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd    ">    <!-- spring扫描service和repository -->    <context:component-scan base-package="ssam">        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>    </context:component-scan></beans>    2.2 配置spring        web.xml中加    <context-param>    <param-name>contextConfigLocation</param-name>    <param-value>classpath:spring.xml</param-value>  </context-param>  <listener>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>    2.3配置消息转换器        Springmvc.xml中添加        <!-- 配置消息转换器MappingJackson2HttpMessageConverter -->    <mvc:annotation-driven>        <mvc:message-converters><!-- 数组转换器 -->            <bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter">                <property name="supportedMediaTypes">                    <list>                        <value>text/html</value>                        <value>application/x-www-form-urlencoded</value>                    </list>                </property>            </bean>        <!-- 对象转换器 -->            <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">                <property name="supportedMediaTypes">                    <list>                        <value>text/html</value>                        <value>application/x-www-form-urlencoded</value>                    </list>                </property>            </bean>        </mvc:message-converters>    </mvc:annotation-driven>2.4 配置数据源        这里使用druid    Pom.xml中添加<dependency>        <groupId>com.alibaba</groupId>            <artifactId>druid</artifactId>            <version>1.1.5</version></dependency><dependency>            <groupId>mysql</groupId>            <artifactId>mysql-connector-java</artifactId>            <version>5.1.6</version></dependency>    spring.xml添加    <!-- 配置数据源 -->    <context:property-placeholder location="class:jdbc.properties"/>    <bean id="datasource" class="com.alibaba.druid.pool.DruidDataSource">        <property name="url" value="${url}"></property>        <property name="username" value="${username1}"></property>        <property name="password" value="${password}"></property>        <property name="driverClassName" value="${driverClass}"></property>        <property name="initialSize" value="1"></property>        <property name="maxActive" value="200"></property>          <property name="maxIdle" value="100"></property>        <property name="filters" value="stat"></property>    </bean>

3.mybatis

3.1 添加依赖    Pom.xml添加    <dependency>     <groupId>org.mybatis</groupId>        <artifactId>mybatis-spring</artifactId>     <version>1.2.3</version></dependency><dependency>            <groupId>org.mybatis</groupId>            <artifactId>mybatis</artifactId>            <version>3.2.8</version></dependency>3.2 配置session工厂Pom.xml中添加<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">        <property name="dataSource" ref="dataSource"></property>    </bean>    <bean id="sessionTemplate" class="org.mybatis.spring.SqlSessionTemplate"><constructor-arg index="0" ref="sqlSessionFactory"></constructor-arg>   </bean><!-- 扫描mybatis接口映射 -->    <bean id="scannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">        <property name="basePackage" value="ssam.mapper"></property>    </bean>3.3 配置事务    <!-- 事务管理器 -->    <bean id="tm" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="datasource"></property></bean>    <tx:advice id="txAdvice" transaction-manager="tm">        <tx:attributes>            <tx:method name="delete*" propagation="REQUIRED"/>            <tx:method name="add*" propagation="REQUIRED"/>            <tx:method name="update*" propagation="REQUIRED"/>            <tx:method name="*" read-only="true"/>        </tx:attributes>    </tx:advice>    <aop:config>        <aop:pointcut expression="execution(* ssam.service.*.*(..))" id="myPonintCut"/>        <!-- 管联切点和事务管理器 -->        <aop:advisor advice-ref="txAdvice" pointcut-ref="myPointCut"/>    </aop:config>

4.AJAX

    //封装ajax    function sendAjax(url, methodType, param, retnFunction) {        //首先创建xmlhttp对象        var xmlhttp = null;        //根据浏览器创建不同的对象,兼容所有浏览器(XHR)        if (window.XMLHttpRequest) {//适应 IE7+, Firefox, Chrome, Opera, Safari            xmlhttp = new XMLHttpRequest();        } else {// 适应 IE6, IE5            xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");        }        //readyState 存有 XMLHttpRequest 的状态。从 0 到 4 发生变化。0: 请求未初始化        //1: 服务器连接已建立        //2: 请求已接收        //3: 请求处理中        //4: 请求已完成，且响应已就绪        //status 状态码 200: "OK"  404: 未找到页面（还有很多）        xmlhttp.onreadystatechange = function() {            if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {                retnFunction(xmlhttp.responseText);            }        }        if (methodType.toUpperCase() == "GET") {            xmlhttp.open("GET", url + "?" + param, true);            xmlhttp.send();        } else {            xmlhttp.open("POST", url, true);            xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded;charset=UTF-8");            alert(param);            xmlhttp.send(param);        }    }

5.配置druid监控

web.xml添加<!-- druid监控 -->    <servlet>        <servlet-name>statViewServlet</servlet-name>        <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class>        <init-param>            <param-name>loginUsername</param-name>            <param-value>admin</param-value>        </init-param>        <init-param>            <param-name>loginPassword</param-name>            <param-value>zyp</param-value>        </init-param>        <load-on-startup>1</load-on-startup>    </servlet>    <servlet-mapping>        <servlet-name>statViewServlet</servlet-name>        <url-pattern>/druid/*</url-pattern>    </servlet-mapping>
