[javaWeb] IDEA进行SSM框架整合

一、创建Maven项目

二、配置pom文件

其中关于引入的各个jar包的作用，大部分都添加了注释，个别的自己项目用不到的内容，可自行取舍。

  </dependencies>

三、创建相关的包结构

这里因为博主为了截图，创建了不止一次项目，所以不必过分纠结于项目名。

四、 web.xml配置ServletDispathcer拦截

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
                      http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1" metadata-complete="true">
  <display-name>Archetype Created Web Application</display-name>
  <servlet>
    <servlet-name>spring-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring/spring-*.xml</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>spring-dispatcher</servlet-name>
    <!--默认匹配所有请求-->
    <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>

五、Spring相关配置文件配置

spring-dao.xml

spring整合mybatis

<?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.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="com.mchange.v2.c3p0.ComboPooledDataSource">
        <!-- 配置连接池属性 -->
        <property name="driverClass" value="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>

        <!-- c3p0连接池的私有属性 -->
        <property name="maxPoolSize" value="30"/>
        <property name="minPoolSize" value="10"/>
        <!-- 关闭连接后不自动commit -->
        <property name="autoCommitOnClose" value="false"/>
        <!-- 获取连接超时时间 -->
        <property name="checkoutTimeout" value="10000"/>
        <!-- 当获取连接失败重试次数 -->
        <property name="acquireRetryAttempts" value="2"/>
    </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:mybatis-config.xml -->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
        <!-- 扫描entity包 使用别名 -->
        <property name="typeAliasesPackage" value="com.qcby.entity"/>
        <!-- 扫描sql配置文件:mapper需要的xml文件 -->
        <property name="mapperLocations" value="classpath:mapper/*.xml"/>
    </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.qcby.dao"/>
    </bean>
</beans>

spring-service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"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
    <?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.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.qcby.service" />

        <!-- 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>
</beans>

spring-web

控制层相关内容配置

<?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:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
	http://www.springframework.org/schema/beans/spring-beans.xsd
	http://www.springframework.org/schema/context
	http://www.springframework.org/schema/context/spring-context.xsd
	http://www.springframework.org/schema/mvc
	http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
	http://www.springframework.org/schema/aop
	http://www.springframework.org/schema/aop/spring-aop.xsd">

    <!-- **组件扫描功能,扫描aop的相关组件组件 -->
    <!--<context:component-scan base-package="org.seckill.aop"/>-->
    <!-- 启动对@AspectJ注解的支持 -->
    <!--<aop:aspectj-autoproxy proxy-target-class="false"/>-->

    <!-- 配置SpringMVC -->
    <!-- 1.开启SpringMVC注解模式 -->
    <!-- 简化配置：
        (1)自动注册DefaultAnootationHandlerMapping,AnotationMethodHandlerAdapter
        (2)提供一些列：数据绑定，数字和日期的format @NumberFormat, @DateTimeFormat, xml,json默认读写支持
    -->
    <mvc:annotation-driven/>

    <!-- 2.静态资源默认servlet配置
        (1)加入对静态资源的处理：js,gif,png
        (2)允许使用"/"做整体映射
     -->
    <mvc:resources mapping="/resources/**" location="/resources/"/>
    <mvc:default-servlet-handler/>

    <!-- 3.定义视图解析器
    配置jsp 显示ViewResolver -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/html/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

    <!-- 4.扫描web相关的bean -->
    <context:component-scan base-package="com.qcby.controller"/>
</beans>

六、数据库配置文件

这里配置的是新版的mysql8.0的连接url，设置不使用ssl连接

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/your_database_name?characterEncoding=utf8&useSSL=false&serverTimezone=UTC&rewriteBatchedStatements=true
jdbc.username=root
jdbc.password=root

七、mybatis-config配置

<?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>
    <!-- 配置全局属性 -->
    <settings>
        <!-- 使用jdbc的getGeneratedKeys获取数据库自增主键值 -->
        <setting name="useGeneratedKeys" value="true" />

        <!-- 使用列别名替换列名 默认:true -->
        <setting name="useColumnLabel" value="true" />

        <!-- 开启驼峰命名转换:Table{create_time} -> Entity{createTime} -->
        <setting name="mapUnderscoreToCamelCase" value="true" />
        <!-- 打印查询语句 -->
        <setting name="logImpl" value="STDOUT_LOGGING" />
    </settings>
</configuration>

八、测试

数据库测试

import org.springframework.stereotype.Repository;

import java.util.Date;

@Repository
public class Area {
    private Integer area_id;

    private String area_name;

    private String area_desc;

    private Integer priority;

    private Date create_time;

    private Date last_edit_time;

    public Integer getArea_id() {
        return area_id;
    }

    public void setArea_id(Integer area_id) {
        this.area_id = area_id;
    }

    public String getArea_name() {
        return area_name;
    }

    public void setArea_name(String area_name) {
        this.area_name = area_name == null ? null : area_name.trim();
    }

    public String getArea_desc() {
        return area_desc;
    }

    public void setArea_desc(String area_desc) {
        this.area_desc = area_desc == null ? null : area_desc.trim();
    }

    public Integer getPriority() {
        return priority;
    }

    public void setPriority(Integer priority) {
        this.priority = priority;
    }

    public Date getCreate_time() {
        return create_time;
    }

    public void setCreate_time(Date create_time) {
        this.create_time = create_time;
    }

    public Date getLast_edit_time() {
        return last_edit_time;
    }

    public void setLast_edit_time(Date last_edit_time) {
        this.last_edit_time = last_edit_time;
    }

    @Override
    public String toString() {
        return "Area{" +
                "area_id=" + area_id +
                ", area_name='" + area_name + '\'' +
                ", area_desc='" + area_desc + '\'' +
                ", priority=" + priority +
                ", create_time=" + create_time +
                ", last_edit_time=" + last_edit_time +
                '}';
    }
}

import com.qcby.entity.Area;

import java.util.List;

public interface AreaDao {

    List<Area> queryArea();
}

import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

/**
 *配置spring和junit整合，junit启动时加载springIoc容器
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:spring/spring-dao.xml"})
public class BaseTest {
}

import com.qbcy.BaseTest;
import com.qcby.entity.Area;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;

import java.util.Date;
import java.util.List;

import static junit.framework.TestCase.assertEquals;

public class AreaDaoTest extends BaseTest {

    @Autowired
    private com.qcby.dao.AreaDao areaDao;

    @Test
    public void testQueryArea(){
        List<Area> areaList = areaDao.queryArea();
        System.out.println(areaList);
        Area area = new Area();
        area.setArea_name("zhongguo");
        area.setPriority(3);
        area.setCreate_time(new Date());
        area.setLast_edit_time(new Date());
        areaDao.addArea(area);
        assertEquals(4,areaList.size());
    }

}

出现下面图片的数据库内容证明测试通过：

Service和Controller测试

import com.qcby.service.Impl.TestService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest;

@Controller
@RequestMapping("test")
public class TestController {

    @Autowired
    TestService testService;

    @RequestMapping("testcon")
    public String testCon(Model model, HttpServletRequest request){
        request.setAttribute("test","testcontent");
        testService.testService();
        return "test";
    }
}

@Service("testService")
public class TestService {
    public void testService(){
        System.out.println("TestService");
    }
}

最后出现我们设置的testcontent就万事大吉啦！
