注意：这里使用jdk1.7版本
文件报错是因为jdk版本太高jdk1.7版本就不报错
框架搭建
一、web.xml配置
1 <?xml version="1.0" encoding="UTF-8"?> 2 <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"> 3 <display-name>SSM03</display-name> 4 <!-- 运行欢迎页 --> 5 <welcome-file-list> 6 <welcome-file>index.jsp</welcome-file> 7 </welcome-file-list> 8 9 <!--SSM整合框架 --> 10 <!-- spring的核心配置 --> 11 <!--配置spring上下文 --> 12 <context-param> 13 <param-name>contextConfigLocation</param-name> 14 <!-- 这里要扫描spring设置 和spring里mybatis的设置--> 15 <param-value>classpath:applicationContext.xml</param-value> 16 </context-param> 17 <!-- 配置spring监听器 --> 18 <listener> 19 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 20 </listener> 21 <!-- SpringMVC核心配置 --> 22 <!-- 配置SpringMVC核心控制器 --> 23 <servlet> 24 25 <servlet-name>springmvc</servlet-name> 26 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 27 28 29 <!-- contextConfigLocation配置springmvc加载的配置文件（配置处理器映射器、适配器等等） 30 如果不配置contextConfigLocation，默认加载的是/WEB-INF/servlet名称-serlvet.xml（springmvc-servlet.xml） --> 31 32 <init-param> 33 <param-name>contextConfigLocation</param-name> 34 <!-- 这里要扫描springmvc的跳转和传输设置 --> 35 36 <param-value>classpath:spring-mvc.xml</param-value> 37 </init-param> 38 <!-- 优先等及 --> 39 <load-on-startup>1</load-on-startup> 40 </servlet> 41 42 <servlet-mapping> 43 <servlet-name>springmvc</servlet-name> 44 <url-pattern>*.do</url-pattern> 45 </servlet-mapping> 46 47 <!-- post乱码过虑器 --> 48 <filter> 49 <filter-name>CharacterEncodingFilter</filter-name> 50 <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> 51 <init-param> 52 <param-name>encoding</param-name> 53 <param-value>utf-8</param-value> 54 </init-param> 55 </filter> 56 <filter-mapping> 57 <filter-name>CharacterEncodingFilter</filter-name> 58 <url-pattern>/*</url-pattern> 59 </filter-mapping> 60 61 62 63 <!-- Mybatis核心配置 --> 64 <!-- 对于数据持久层的框架而言，都交给spring处理 --> 65 66 67 68 </web-app>
二、配置spring-mvc.xml
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd "> <!-- 开启springmvc --> <context:annotation-config /> <!-- 注解扫描包 --> <context:component-scan base-package="com.ssm.controller" /> <context:component-scan base-package="com.ssm.service" /> <!-- 定义跳转的文件的前后缀 ，视图模式配置--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/jsp/"></property> <property name="suffix" value=".jsp"></property> </bean> </beans>
三、配置spring(applicationContext.xml)
1 <beans xmlns="http://www.springframework.org/schema/beans" 2 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" 3 xmlns:context="http://www.springframework.org/schema/context" 4 xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" 5 xsi:schemaLocation="http://www.springframework.org/schema/beans 6 http://www.springframework.org/schema/beans/spring-beans-3.2.xsd 7 http://www.springframework.org/schema/mvc 8 http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd 9 http://www.springframework.org/schema/context 10 http://www.springframework.org/schema/context/spring-context-3.2.xsd 11 http://www.springframework.org/schema/aop 12 http://www.springframework.org/schema/aop/spring-aop-3.2.xsd 13 http://www.springframework.org/schema/tx 14 http://www.springframework.org/schema/tx/spring-tx-3.2.xsd "> 15 16 17 <!-- IOC --> 18 <!-- web.xml交给spring配置的东西 --> 19 <!-- 配置mybatis --> 20 <!-- 导入数据源 ，dbcp --> 21 <context:property-placeholder location="classpath:db.properties" /> 22 <!-- 配置数据源 ，dbcp --> 23 24 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" 25 destroy-method="close"> 26 <property name="driverClassName" value="${jdbc.driver}" /> 27 <property name="url" value="${jdbc.url}" /> 28 <property name="username" value="${jdbc.username}" /> 29 <property name="password" value="${jdbc.password}" /> 30 </bean> 31 32 <!-- 创建sqlSessionFactory --> 33 <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> 34 <!-- 数据源（数据库连接池） --> 35 <property name="dataSource" ref="dataSource" /> 36 <!-- 加载mybatis的全局配置文件 --> 37 <property name="configLocation" value="classpath:mybatis-Config.xml" /> 38 </bean> 39 40 <!-- mapper扫描器 --> 41 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> 42 <!-- 扫描包路径，如果需要扫描多个包，中间使用半角逗号隔开 --> 43 <property name="basePackage" value="com.ssm.mapper"></property> 44 <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> 45 </bean> 46 47 <!-- AOP:16个字 --> 48 <!-- 事务管理 --> 49 <!-- 创建事务管理器 --> 50 <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> 51 <!-- 数据源 --> 52 <property name="dataSource" ref="dataSource"/> 53 </bean> 54 55 <!-- 创建通知：事务管理器管理通知 --> 56 <tx:advice id="txAdvice" transaction-manager="transactionManager"> 57 <tx:attributes> 58 <!-- 传播行为 --> 59 <tx:method name="save*" propagation="REQUIRED"/> 60 <tx:method name="delete*" propagation="REQUIRED"/> 61 <tx:method name="insert*" propagation="REQUIRED"/> 62 <tx:method name="update*" propagation="REQUIRED"/> 63 <tx:method name="find*" propagation="SUPPORTS" read-only="true"/> 64 <tx:method name="get*" propagation="SUPPORTS" read-only="true"/> 65 <tx:method name="select*" propagation="SUPPORTS" read-only="true"/> 66 </tx:attributes> 67 </tx:advice> 68 69 <!-- 要扫描的serviceImpl包 aop --> 70 <aop:config> 71 <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.ssm.service.*.*(..))"/> 72 </aop:config> 73 74 </beans>
四、
1.创建db.properties，并赋值
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/hahaha
jdbc.username=root
jdbc.password=123456
2.mybatis的全局配置文件（mybatis-config.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> <!-- 全局setting配置，根据需要添加 --> <!-- 配置别名 --> <typeAliases> <!-- 批量扫描别名 --> <package name="com.ssm.po"/> </typeAliases> <!-- 配置mapper 由于使用spring和mybatis的整合包进行mapper扫描，这里不需要配置了。 必须遵循：mapper.xml和mapper.java文件同名且在一个目录 --> <!-- <mappers> </mappers> --> </configuration>
写入项目
如图
一、创建实例对象（t_role.java）
1 package com.ssm.entity; 2 3 public class t_role { 4 private int id; 5 private String tname; 6 private String phon; 7 private String endtimes; 8 private String sname; 9 public int getId() { 10 return id; 11 } 12 public void setId(int id) { 13 this.id = id; 14 } 15 public String getTname() { 16 return tname; 17 } 18 public void setTname(String tname) { 19 this.tname = tname; 20 } 21 public String getPhon() { 22 return phon; 23 } 24 public void setPhon(String phon) { 25 this.phon = phon; 26 } 27 public String getEndtimes() { 28 return endtimes; 29 } 30 public void setEndtimes(String endtimes) { 31 this.endtimes = endtimes; 32 } 33 public String getSname() { 34 return sname; 35 } 36 public void setSname(String sname) { 37 this.sname = sname; 38 } 39 public t_role() { 40 41 } 42 public t_role(int id, String tname, String phon, String endtimes, String sname) { 43 this.id = id; 44 this.tname = tname; 45 this.phon = phon; 46 this.endtimes = endtimes; 47 this.sname = sname; 48 } 49 @Override 50 public String toString() { 51 return "t_role [id=" + id + ", tname=" + tname + ", phon=" + phon + ", endtimes=" + endtimes + ", sname=" 52 + sname + "]"; 53 } 54 55 56 57 58 59 }
二、创建tMapper.java和tMapper.xml
tMapper.java
package com.ssm.mapper; import java.util.List; import com.ssm.entity.t_role; public interface tMapper { void save(t_role t_role); int update(t_role t_role); boolean delete(int id); t_role findById(int id); List<t_role> findAll(); }
tMapper.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.ssm.mapper.tMapper"> <!-- 添加 --> <insert id="save" parameterType="com.ssm.entity.t_role"> INSERT INTO t_role(id,tname,phon,endtimes,sname) VALUES(#{id},#{tname},#{phon},#{endtimes},#{sname}) </insert> <!-- 修改 --> <update id="update" parameterType="com.ssm.entity.t_role"> UPDATE t_role SET tname=#{tname},phon=#{phon},endtimes=#{endtimes},sname=#{sname} where id=#{id} </update> <!-- 删除 --> <delete id="delete" parameterType="int"> DELETE FROM t_role WHERE id=#{id} </delete> <!-- 查询 --> <select id="findById" parameterType="int" resultType="com.ssm.entity.t_role"> SELECT * FROM t_role WHERE id=#{id} </select> <!-- 查询 --> <select id="findAll" resultType="com.ssm.entity.t_role"> SELECT * FROM t_role </select> <!-- 分页 --> <select id="selectUsersByPage" parameterType="int" resultType="com.ssm.entity.t_role"> SELECT TOP 10 * FROM (SELECT ROW_NUMBER() OVER (ORDER BY ID) AS ROWNUMBER,* FROM t_role ) AS A WHERE ROWNUMBER>10*(#{page}-1) </select> </mapper>
三、创建tservice.java和tserviceImpl.java
tservice.java
package com.ssm.service; import java.util.List; import com.ssm.entity.t_role; public interface tservice { void save(t_role t_role); int update(t_role t_role); boolean delete(int id); t_role findById(int id); List<t_role> findAll(); }
tserviceImpl.java
1 package com.ssm.service; 2 3 import java.util.List; 4 5 import javax.annotation.Resource; 6 7 import org.springframework.beans.factory.annotation.Autowired; 8 import org.springframework.stereotype.Service; 9 import[java]整合SSM框架实现简单的增删改查Struts2+Spring+Hibernate实现员工管理增删改查功能之ssh框架整合
