web項目SSM框架搭建

SSM框架整合配置初始模板

使用idea工具，並使用了maven父工程模板（集中定義管理依賴版本）

打開父工程文件

新建module

開始整合配置

使用的依賴版本號

    <!-- 集中定義依賴版本號 -->
    <properties>
        <junit.version>4.12</junit.version>
        <spring.version>5.0.7.RELEASE</spring.version>
        <mybatis.version>3.4.6</mybatis.version>
        <mybatis.spring.version>1.3.2</mybatis.spring.version>
        <mybatis.paginator.version>1.2.15</mybatis.paginator.version>
        <mysql.version>5.1.32</mysql.version>

        <commons-io.version>1.3.2</commons-io.version>
    </properties>

第一步、spring和springMVC整合

1.1、引入module所需依賴和插件

            </plugin>
        </plugins>
    </build>

注意：在子模塊pom文件中添加打包方式，以及補全web項目目錄結構。

1.2、配置spring

​ 首先配置jdbc和log4j配置文件，放在resource裏面，並新建一個專門存放 spring配置文件的文件夾，新建spring核心配置文件

1.2.1配置spring核心配置文件

<?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: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/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <!-- 開啓註解掃描,在這裏只掃描service包，controller交給springMVC掃描，mapper包使用mybatis不用掃描註解 -->
    <context:component-scan base-package="com.lee.service"/>

    <!--引入jdbc配置文件-->
    <context:property-placeholder location="classpath:jdbc.properties"/>

    <!--jdbc參數-->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="${jdbc.driverClassName}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>
</beans>

1.2.2在web.xml文件中配置spring核心監聽器

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
		  http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
           version="3.0">
    
    <!--配置spring核心監聽器，在項目加載時就創建spring IOC容器-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

</web-app>

1.2.3創建IOC容器需要spring配置文件，加載spring配置文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
		  http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
           version="3.0">

    <!--加載spring配置文件-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:/spring/applicationContext*.xml</param-value>
    </context-param>

    <!--配置spring核心監聽器，在項目加載時就創建spring IOC容器-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

</web-app>

1.3、配置SpringMVC

1.3.1在web.xml文件中指定springMVC入口

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"          xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
		  http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
           version="3.0">

    <!--加載spring配置文件-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:/spring/applicationContext*.xml</param-value>
    </context-param>

    <!--配置spring核心監聽器，在項目加載時就創建spring IOC容器-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!--配置springMVC入口-->
    <servlet>
        <servlet-name>springMVC</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!--配置springMVC文件路徑-->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:/spring/springMVC-servlet.xml</param-value>
        </init-param>
        <!--配置實例化時機，默認第一次請求時實例化，設爲0或正數則爲項目時加載時並實例化-->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springMVC</servlet-name>
        <!--匹配攔截所有請求，除了jsp-->
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

1.3.2配置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: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/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!--開啓註解掃描-->
    <context:component-scan base-package="com.lee.controller"/>

    <!--註解驅動-->
    <mvc:annotation-driven/>

    <!--解決靜態資源(html,js,css)被攔截-->
    <mvc:default-servlet-handler/>

    <!--配置視圖解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

1.4、測試spring和springMVC

1.4.1在WEB-INF/jsp文件下創建一個test.jsp文件

<%--
  Created by IntelliJ IDEA.
  User: LxY
  Date: 2018/11/19
  Time: 12:07
  To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
    測試spring和SpringMVC
</body>
</html>

1.4.2在controller包下創建TestController

package com.lee.controller;

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

    @RequestMapping("ss")
    public String test(){
        return "test";
    }
}

運行結果：

1.5、配置mybatis

1.5.1spring-mybatis配置文件

​ 在配置文件spring包中創建applicationContext-mybatis.xml配置文件，配置spring管理mybatis的配置

<?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">

    <!--把SQLSession交給spring管理-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!--注入數據源-->
        <property name="dataSource" ref="dataSource"/>
        <!--注入mybatis配置文件-->
        <property name="configLocation" value="classpath:mybatis/mybatis-config.xml"/>
        <!--注入映射文件路徑-->
        <property name="mapperLocations" value="classpath:mybatis/mapper/**/*.xml"/>
        <!--別名管理-->
        <property name="typeAliasesPackage" value="com.lee.domain"/>
    </bean>

    <!--把mapper接口交給spring管理-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.lee.mapper"/>
    </bean>

</beans>

1.5.2mybatis.xml文件配置

​ 只需要配置一個駝峯匹配即可

<?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>
    <settings>
        <!--開啓駝峯匹配-->
        <setting name="mapUnderscoreToCamelCase" value="true"/>
    </settings>

</configuration>

1.6、測試mybatis配置

1.6.1數據庫準備

​ 準備一張簡單用戶表

1.6.2編寫對應實體類

package com.lee.domain;

public class User implements Serializable{

	private static final long serialVersionUID = 1L;

	private Long id;

    // 用戶名
    private String userName;

    // 密碼
    private String password;

    // 姓名
    private String name;

    // 年齡
    private Integer age;

    // 性別，1男性，2女性
    private Integer sex;

    // 出生日期
    private Date birthday;

    // 創建時間
    private Date created;

    // 更新時間
    private Date updated;

    public Long getId() {
        return id;
    }

    public void setId(Long 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 String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public Integer getSex() {
        return sex;
    }

    public void setSex(Integer sex) {
        this.sex = sex;
    }

    public Date getBirthday() {
        return birthday;
    }

    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }

    public Date getCreated() {
        return created;
    }

    public void setCreated(Date created) {
        this.created = created;
    }

    public Date getUpdated() {
        return updated;
    }

    public void setUpdated(Date updated) {
        this.updated = updated;
    }

    @Override
    public String toString() {
        return "User [id=" + id + ", userName=" + userName + ", password=" + password + ", name=" + name
                + ", age=" + age + ", sex=" + sex + ", birthday=" + birthday + ", created=" + created
                + ", updated=" + updated + "]";
    }

}

1.6.3編寫UserMapper接口

package com.lee.mapper;

public interface UserMapper {

    /**
     * 查找所有用戶信息
     * @return
     */
    List<User> findAllUser();
}

1.6.4編寫userMapper.xml文件

<?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.lee.mapper.UserMapper">
	<!--查找所有用戶信息-->
    <select id="findAllUser" resultType="User">
        select * from tb_user
    </select>
    
</mapper>

1.6.5編寫對應的測試單元

package com.lee.test;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:spring/applicationContext*.xml")
public class UserTest {

    @Autowired
    private UserMapper userMapper;

    @Test
    public void test1() {
        List<User> list = userMapper.findAllUser();
        for (User user : list) {
            System.out.println(user);
        }
    }
}

遇到問題：

​ 第一次報錯內容如下：

原因：

​ applicationContext-mybatis.xml 配置文件中配置錯誤，

<!--別名管理-->
        <property name="typeAliases" value="com.lee.domain"/>

​ 修改爲：

<!--別名管理-->
        <property name="typeAliasesPackage" value="com.lee.domain"/>

運行正確後測試結果：

1.7、配置事務

1.7.1在spring中配置事務

​ 在資源包spring下創建applicationContext-tx.xml事務配置文件

<?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: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.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd">

    <!--配置事務管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <!--其中ref可能會報紅，應該是軟件問題，把項目關了再開就解決-->
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <!--配置事務屬性-->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <!--配置查詢數據庫的方法中find開頭的只讀-->
            <tx:method name="find*" read-only="true"/>
            <!--配置其他方法可讀寫（默認）-->
            <tx:method name="*"/>
        </tx:attributes>
    </tx:advice>

    <!--配置事務切面-->
    <aop:config>
        <aop:pointcut id="pointcut" expression="execution(* com.lee.service.impl.*.*(..))"/>
    </aop:config>
</beans>
        

1.8、總結

​ 至此SSM框架簡單配置已經完整。

1.9、附上整體項目目錄結構
