web项目SSM框架搭建

SSM框架整合配置初始模板

使用idea工具，并使用了maven父工程模板（集中定义管理依赖版本）

打开父工程文件

新建module

开始整合配置

使用的依赖版本号

    
    
        4.12
        5.0.7.RELEASE
        3.4.6
        1.3.2
        1.2.15
        5.1.32
        1.6.4
        2.9.0
        1.3.1
        1.0.9
        4.3.5
        1.2
        2.5
        2.0
        2.5
        3.3.2
        1.3.2
    

第一步、spring和springMVC整合

1.1、引入module所需依赖和插件

注意：在子模块pom文件中添加打包方式，以及补全web项目目录结构。

1.2、配置spring

​ 首先配置jdbc和log4j配置文件，放在resource里面，并新建一个专门存放 spring配置文件的文件夹，新建spring核心配置文件

1.2.1配置spring核心配置文件

<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">
    
    <context:component-scan base-package="com.lee.service"/>

    
    <context:property-placeholder location="classpath:jdbc.properties"/>

    
    <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核心监听器

<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">
    
    
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
    listener>

web-app>

1.2.3创建IOC容器需要spring配置文件，加载spring配置文件

<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">

    
    <context-param>
        <param-name>contextConfigLocationparam-name>
        <param-value>classpath:/spring/applicationContext*.xmlparam-value>
    context-param>

    
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
    listener>

web-app>

1.3、配置SpringMVC

1.3.1在web.xml文件中指定springMVC入口

<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">

    
    <context-param>
        <param-name>contextConfigLocationparam-name>
        <param-value>classpath:/spring/applicationContext*.xmlparam-value>
    context-param>

    
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
    listener>

    
    <servlet>
        <servlet-name>springMVCservlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
        
        <init-param>
            <param-name>contextConfigLocationparam-name>
            <param-value>classpath:/spring/springMVC-servlet.xmlparam-value>
        init-param>
        
        <load-on-startup>1load-on-startup>
    servlet>
    <servlet-mapping>
        <servlet-name>springMVCservlet-name>
        
        <url-pattern>/url-pattern>
    servlet-mapping>
web-app>

1.3.2配置springMVC配置文件

​

<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">

    
    <context:component-scan base-package="com.lee.controller"/>

    
    <mvc:annotation-driven/>

    
    <mvc:default-servlet-handler/>

    
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    bean>
beans>

1.4、测试spring和springMVC

1.4.1在WEB-INF/jsp文件下创建一个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" %>


    


    测试spring和SpringMVC

1.4.2在controller包下创建TestController

package com.lee.controller;

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

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

运行结果：

1.5、配置mybatis

1.5.1spring-mybatis配置文件

​ 在配置文件spring包中创建applicationContext-mybatis.xml配置文件，配置spring管理mybatis的配置

<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">

    
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        
        <property name="dataSource" ref="dataSource"/>
        
        <property name="configLocation" value="classpath:mybatis/mybatis-config.xml"/>
        
        <property name="mapperLocations" value="classpath:mybatis/mapper/**/*.xml"/>
        
        <property name="typeAliasesPackage" value="com.lee.domain"/>
    bean>

    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.lee.mapper"/>
    bean>

beans>

1.5.2mybatis.xml文件配置

​ 只需要配置一个驼峰匹配即可

<configuration>
    <settings>
        
        <setting name="mapUnderscoreToCamelCase" value="true"/>
    settings>

configuration>

1.6、测试mybatis配置

1.6.1数据库准备

​ 准备一张简单用户表

1.6.2编写对应实体类

package com.lee.domain;

public class User implements Serializable{

	private static final long serialVersionUID = 1L;

	private Long id;

    // 用户名
    private String userName;

    // 密码
    private String password;

    // 姓名
    private String name;

    // 年龄
    private Integer age;

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

    // 出生日期
    private Date birthday;

    // 创建时间
    private Date created;

    // 更新时间
    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编写UserMapper接口

package com.lee.mapper;

public interface UserMapper {

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

1.6.4编写userMapper.xml文件

<mapper namespace="com.lee.mapper.UserMapper">
	
    <select id="findAllUser" resultType="User">
        select * from tb_user
    select>
    
mapper>

1.6.5编写对应的测试单元

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);
        }
    }
}

遇到问题：

​ 第一次报错内容如下：

原因：

​ applicationContext-mybatis.xml 配置文件中配置错误，

        <property name="typeAliases" value="com.lee.domain"/>

​ 修改为：

        <property name="typeAliasesPackage" value="com.lee.domain"/>

运行正确后测试结果：
