2、整合springmvc：
（1）在web.xml文件中配置前端控制器：
<?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_2_5.xsd" id="servicemarket" version="2.5"> <display-name>ssm-test</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <!-- 加载spring相关配置文件 --> <context-param> <param-name>contextconfiglocation</param-name> <param-value>classpath:spring/applicationcontext*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.contextloaderlistener</listener-class> </listener> <!-- 解决post乱码 --> <filter> <filter-name>characterencodingfilter</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> </filter> <filter-mapping> <filter-name>characterencodingfilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- springmvc的前端控制器 --> <servlet> <servlet-name>ssm-test</servlet-name> <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class> <!-- 加载springmvc的配置文件(处理器映射器、处理器适配器等等) --> <init-param> <param-name>contextconfiglocation</param-name> <param-value>classpath:spring/springmvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>ssm-test</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
（2）编写springmvc.xml文件：
在文件中配置与springmvc框架相关的配置，比如：springmvc.xml约束、处理器映射器、处理器适配器、视图解析器、handler等配置。
<?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: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/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.xsd">
<!-- 使用注解驱动：自动配置处理器映射器与处理器适配器 -->
<mvc:annotation-driven />
<!-- 注解方式：配置handler，自动扫描该包，使springmvc认为包下用了@controller注解的类是控制器 -->
<!-- 批量加载：组件扫描方式： -->
<context:component-scan base-package="com.zwp.controller" />
<!-- 视图解析器：解析jsp页面，默认使用jstl标签，classpath下得有jstl的包 -->
<bean class="org.springframework.web.servlet.view.internalresourceviewresolver">
<!-- 配置前后缀 -->
<property name="prefix" value="/web-inf/jsp/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<!-- 静态资源处理，不拦截静态资源，如css、js、imgs -->
<mvc:resources location="/static/css/" mapping="/static/css/**"/>
<mvc:resources location="/static/js/" mapping="/static/js/**"/>
<mvc:resources location="/static/img/" mapping="/static/img/**"/>
<!-- 文件上传相关配置 -->
<bean id="multipartresolver"
class="org.springframework.web.multipart.commons.commonsmultipartresolver">
<property name="defaultencoding" value="utf-8"></property>
<property name="maxuploadsize" value="10240000"></property>
</bean>
</beans>
（3）编写handler：
//user类的handler
//需要在类上面加@controller注解，这样才能被自动扫描到
@controller
@requestmapping("/user")
public class usercontroller {
private static logger log=loggerfactory.getlogger(usercontroller.class);
@requestmapping(value="/login",method=requestmethod.get)
public string login(httpservletrequest request,model model){
string username = request.getparameter("username");
string password = request.getparameter("password");
system.out.println("username:"+username+";password:"+password);
user user=null;
if (username.equals("zwp") && password.equals("123456")) {
user = new user();
user.setage(11);
user.setid(1);
user.setpassword("123456");
user.setusername("zwp");
log.debug(user.tostring());
}
model.addattribute("user", user);
return "index";
}
}
//user实体类
public class user {
private integer id;
private string username;
private string password;
private integer age;
public integer getid() {
return id;
}
public void setid(integer id) {
this.id = id;
}
public string getusername() {
return username;
}
public void setusername(string username) {
this.username = username;
}
public string getpassword() {
return password;
}
public void setpassword(string password) {
this.password = password;
}
public integer getage() {
return age;
}
public void setage(integer age) {
this.age = age;
}
@override
public string tostring() {
return "user [id=" + id + ", username=" + username + ", password=" + password + ", age=" + age + "]";
}
}
（4）配置日志文件：
在项目根目录下面创建log4j.properties日志文件，下面是日志文件的基本配置，可以满足大多数项目的需求。
log4j.rootlogger=info,console,file
#定义日志输出目的地为控制台
log4j.appender.console=org.apache.log4j.consoleappender
log4j.appender.console.target=system.out
#可以灵活地指定日志输出格式，下面一行是指定具体的格式
log4j.appender.console.layout = org.apache.log4j.patternlayout
log4j.appender.console.layout.conversionpattern=[%c] - %m%n
#文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.file = org.apache.log4j.rollingfileappender
#指定输出目录
log4j.appender.file.file = logs/ssm.log
#定义文件最大大小
log4j.appender.file.maxfilesize = 10mb
# 输出所以日志，如果换成debug表示输出debug以上级别日志
log4j.appender.file.threshold = all
log4j.appender.file.layout = org.apache.log4j.patternlayout
log4j.appender.file.layout.conversionpattern =[%p] [%d{yyyy-mm-dd hh\:mm\:ss}][%c]%m%n
（5）启动项目，进行测试：
访问地址：http://localhost:8080/ssm/user/login?username=zwp&password=123456，如果出现下面页面则代表映射成功。
至此，springmvc的配置就已经成功。
3、spring和mybatis框架的整合：
整合思路：由spring通过单例方式管理sqlsessionfactory；spring和mybatis整合生成代理对象，使用sqlsessionfactory创建sqlsession，持久层的mapper都需要有spring进行管理。
（1）配置dao层，即配置sqlsessionfactory：（我的配置在applicationcontext-dao.xml文件中）
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"
xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
<!-- 1.加载配置文件 -->
<!-- 第一种加载多个.properties文件的方法 -->
<context:property-placeholder location="classpath:resource/*.properties"/>
<!-- 2.配置数据库连接池 -->
<bean id="datasource" class="com.alibaba.druid.pool.druiddatasource"
destroy-method="close">
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="driverclassname" value="${jdbc.driver}" />
<property name="maxactive" value="10" />
<property name="minidle" value="5" />
</bean>
<!-- 3.让spring创建并管理sqlsessionfactory，使用mybatis和spring整合包中的 -->
<bean id="sqlsessionfactory" class="org.mybatis.spring.sqlsessionfactorybean">
<!-- 配置数据源，数据库连接池 -->
<property name="datasource" ref="datasource" />
<!-- 加载mybatis的全局配置文件 -->
<property name="configlocation" value="classpath:mybatis/sqlmapconfig.xml" />
</bean>
<!-- 4.mapper批量扫描：从mapper包中扫描出mapper,自动创建代理对象并且在spring容器中注册
需要遵循规范：mapper接口类名和mapper.xml映射文件名称一致，且在同一目录下，
自动扫描出来的mapper的bean的id为类名(首字母小写)-->
<bean class="org.mybatis.spring.mapper.mapperscannerconfigurer">
<property name="basepackage" value="com.zwp.mapper" />
</bean>
</beans>
创建并编写sqlmapconfig.xml文件：
<?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> <plugins> <!-- com.github.pagehelper为pagehelper类所在包名 --> <plugin interceptor="com.github.pagehelper.pagehelper"> <!-- 设置数据库类型 oracle,mysql,mariadb,sqlite,hsqldb,postgresql六种数据库 --> <property name="dialect" value="mysql" /> </plugin> </plugins> </configuration>
（2）配置service层：（我的配置在applicationcontext-service.xml文件中）
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> <!-- 自动扫描service层的接口与实现类 --> <context:component-scan base-package="com.zwp.service" /> </beans>
（3）配置事务：（我的配置在applicationcontext-trans.xml文件中）
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> <!-- 事务管理器 --> <bean id="transactionmanager" class="org.springframework.jdbc.datasource.datasourcetransactionmanager"> <!-- 数据源 --> <property name="datasource" ref="datasource" /> </bean> <!-- 通知 --> <tx:advice id="txadvice" transaction-manager="transactionmanager"> <tx:attributes> <!-- 传播行为 --> <tx:method name="add*" propagation="required" /> <tx:method name="create*" propagation="required" /> <tx:method name="insert*" propagation="required" /> <tx:method name="save*" propagation="required" /> <tx:method name="update*" propagation="required" /> <tx:method name="delete*" propagation="required" /> <tx:method name="find*" propagation="supports" read-only="true" /> <tx:method name="select*" propagation="supports" read-only="true" /> <tx:method name="get*" propagation="supports" read-only="true" /> </tx:attributes> </tx:advice> <!-- 切面 --> <aop:config> <aop:advisor advice-ref="txadvice" pointcut="execution(* com.zwp.service.*.*(..))" /> </aop:config> </beans>
至此，spring和mybatis框架的整合就完成了。
4、测试：
（1）创建测试用表：
（2）利用mybatis-generator自动创建实体类、mybatis映射文件以及dao接口。
（3）建立service和实现类：
//userservice接口类：
@service
public interface userservice {
public user getuserbyid(int userid);
}
//userservice的实现类
@service
public class userserviceimpl implements userservice {
//注入usermapper接口
@autowired
private usermapper usermapper;
@override
public user getuserbyid(int userid) {
user user = usermapper.selectbyprimarykey(userid);
return user;
}
}
（3）建立usercontroller类：
//user类的handler
//需要在类上面加@controller注解，这样才能被自动扫描到
@controller
@requestmapping("/user")
public class usercontroller {
@autowired
private userservice userservice;
private static logger log=loggerfactory.getlogger(usercontroller.class);
@requestmapping(value="/getuserbyid/{userid}",method=requestmethod.get)
public @responsebody user getuserbyid(@pathvariable integer userid){
return userservice.getuserbyid(userid);
}
@requestmapping(value="/login",method=requestmethod.get)
public string login(httpservletrequest request,model model){
string username = request.getparameter("username");
string password = request.getparameter("password");
system.out.println("username:"+username+";password:"+password);
user user=null;
if (username.equals("zwp") && password.equals("123456")) {
user = new user();
user.setage(11);
user.setid(1);
user.setpassword("123456");
user.setusername("zwp");
log.debug(user.tostring());
}
model.addattribute("user", user);
return "index";
}
}
（4）部署项目，输入地址：http://localhost:8080/ssm/user/getuserbyid/2，出现下面响应结果，则表示整合成功了。
至此，maven+spring+springmvc+mybatis的整合就完成了。
