废话- spring、spring-mvc、mybaties
2018/5/22,自己接触java一年多了,对于流行框SSM,该总结总结了,以备自己查阅资料。(我会整理ssm单独框架使用,对于单独使用某个框架,会加深你对单个框架的理解,很重要。今天就把工作中需要的框架整合整理出来,有工作才能有革命本钱,哈哈,编码不规范哈)。
1 切入正题,一下就是我搭建过程
ssm框架需要的jar包,如果你有疑问,每个jar包都有什么作用,请自己查(别问为什么,先得会搭建,会搭建再刨根问底,jar包我会上传,要是新手自己下载吧)。
2 编写web.xml加载spring和springmvc配置文件
<?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_2_5.xsd"
id="WebApp_ID" version="2.5">

<welcome-file-list>
<welcome-file>index.html</welcome-file>

<!-- 防止乱码得过滤器,粘贴过来使用就可以 -->

<!--contextConfigLocation是 org.springframework.web.context.ContextLoaderListener类固定属性名字 -->

3 编写spring和springmvc配置文件
3.1spring配置文件
<?xml version="1.0" encoding="UTF-8"?>

http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">
<context:component-scan base-package="cn.wazh"></context:component-scan>
<!-- 第一步:配置数据源 -->
<context:property-placeholder location="classpath:config/jdbc.properties" />
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="jdbcUrl" value="${jdbc.url}"></property>
<property name="driverClass" value="${jdbc.driver}"></property>
<property name="user" value="${jdbc.username}"></property>
<property name="password" value="${jdbc.password}"></property>
</bean>
<!-- 第二步:创建sqlSessionFactory。生产sqlSession -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="configLocation" value="classpath:config/sqlMapConfig.xml"></property>
<property name="mapperLocations" value="classpath:com/wazh/dao/*Mapper.xml"></property>
</bean>
<!-- 配置mybatis接口代理开发 * 接口类名和映射文件必须同名 * 接口类和映射文件必须在同一个目录下 * 映射文件namespace名字必须是接口的全类路径名
* 接口的方法名必须和映射Statement的id一致 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.wazh.dao"></property>
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
</bean>
<!-- 第三步:事务 -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<!-- 配置通知 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">

<tx:method name="update*" propagation="REQUIRED" />
<tx:method name="delete*" propagation="REQUIRED" />
<tx:method name="insert*" propagation="REQUIRED" />
<tx:method name="*" propagation="REQUIRED" />
</tx:attributes>
</tx:advice>
<!-- 配置拦截service -->
<aop:config>
<aop:advisor advice-ref="txAdvice"
pointcut="execution(* com.wazh.dao.*.*(..))" />
</aop:config>
</beans>
3.2 springmvc配置文件
<?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: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"

<context:component-scan base-package="com.wazh"></context:component-scan>
<!-- annotation-driven:默认创建了多个对象:RequestMappingHandlerMapping,RequestMappingHandlerAdapter
也就提供对json格式支持 -->
<mvc:annotation-driven />
<!-- 配置sprigmvc视图解析器:解析逻辑试图 后台返回逻辑试图:index 视图解析器解析出真正物理视图:前缀+逻辑试图+后缀====/WEB-INF/jsps/index.jsp -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsps/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<!-- 文件上传解析器 -->
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="maxUploadSize" value="10240000"></property>
</bean>
</beans>
3.3创建一个空的mybaties文件,这里面可以写别名,很有用,我们只是搭建简单得可以用就可以
<?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>
</configuration>
4 创建dao domain service control包
创建一个数据库,一张表(简单点,实现增删改查就可以)
4.1domain层
package com.wazh.domain;
public class Person {
private String name;
private String sex;
private int id;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
@Override
public String toString() {
return "Person [name=" + name + ", sex=" + sex + ", id=" + id + "]";
}
}
4.2dao层
package com.wazh.dao;
import java.util.List;
import com.wazh.domain.Person;
public interface PersonDao {
List<Person> GetAllDao();
int insertPersonDao(Person person);
int deletePersonDao(int id);
Person findPersonByIdDao(int id);
int updateDao(Person person);
}
4.3ampper.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.wazh.dao.PersonDao">
<select id="MakeLove"
resultType="com.wazh.domain.Person">
select * from ren
</select>
<delete id="deletePersonDao" parameterType="int">
DELETE from ren where id=#{id}
</delete>
<!-- <update id="updatePersonDao">
</update>
<insert id="insertPersonDao" parameterType="com.wazh.domain.Person">
</insert> -->
<select id="findPersonByIdDao" parameterType="int" resultType="com.wazh.domain.Person">
select * from ren where id=#{id}
</select>
<update id="updateDao" parameterType="com.wazh.domain.Person" >
update ren set name=#{name},sex=#{sex} where id=#{id}
</update>
<insert id="insertPersonDao" parameterType="com.wazh.domain.Person">
insert into ren values(#{name},#{sex},#{id})
</insert>
</mapper>
4.4service层
package com.wazh.service;
import java.util.List;
import com.wazh.domain.Person;
public interface PersonServicedao {
public List<Person> MakeLoveService();
public int insertPersonService(Person person);
public int deletePersonService(int id);
public Person findPersonByIdService(int id);
public int updateService(Person person);
public int insertService(Person person);
}
4.5control层
package com.wazh.control;
import java.io.IOException;
import java.util.List;
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import com.wazh.domain.Person;
import com.wazh.service.PersonServicedao;
@Controller
public class renController {
@Resource
private PersonServicedao personservice;
@RequestMapping("toMain")
public String toMain(Model model,HttpServletRequest req,HttpServletResponse res) {
System.out.println("toMain方法实现");
List<Person> list=personservice.MakeLoveService();
req.setAttribute("list", list);
return "index";
}
@RequestMapping("update")
public String update(Model model,HttpServletRequest req,int id,HttpServletResponse res) throws IOException {
req.setAttribute("xiaoren", personservice.findPersonByIdService(id));
return "editor";
}
@RequestMapping("saveupdate")
public String saveUpdate(Person person) throws IOException {
int result=personservice.updateService(person);
return "redirect:toMain.do";
}
@RequestMapping("insertready")
public String insertready() throws IOException {
return "add";
}
@RequestMapping("insert")
public String insert(Person person) throws IOException {
personservice.insertService(person);
return "redirect:toMain.do";
}
@RequestMapping("delete")
public String delete(int id) throws IOException {
personservice.deletePersonService(id);
return "redirect:toMain.do";
}
}
5 全部jsp

作为新入行得新手,水平很low,大家见谅哈,(除了会用框架,多问自己框架怎么实现得)有问题一起交流 ,我qq1228029181。
