    利用Intellij+MAVEN搭建Spring+Mybatis+MySql+SpringMVC项目详解

    这两天在公司实习，师父让我先熟悉Intellij软件的使用和SpringMVC框架。话不多说，先利用这些搭建一个小环境吧。

    1 创建MAVEN项目：File-NEW-MAVEN-create from..前打勾--选下面的org.apache..archetypes:maven-archetype-webapp,点击next

                     后面的项目名称：

    GroupId:项目的名称，
    ArtiFactId:项目的模块名称（建议用项目名称-模块名称来表示），
    Version:项目版本的名称
    如：groupID：SpringMVC；ArtiFactId：SpringMVC-Demo，version:默认完成后，IDEA就自动给我们构建了一个空的maven项目.



    2  配置pom.xml文件，这里利用<dependency></dependency>标签导入需要的库。这里需要导入的有junit , spring , springmvc , mysql , mybatis , jstl等等，详见下面的配置文件：

    [html] view plain copy
     
    print?

    3 src下面新建java包，将其设置为source root(在java包上点击右键，选择Mark Directory As Source Root),依次建如图类结构：



    1）创建接口EmployeeMapper.java,这里是采用Mybatis的注解的方式，要在后面的spring-mybatis文件中去注册接口

    [java] view plain copy
     
    print?
    1. package com.mybatis.dao;  
    2.   
    3. import com.mybatis.model.Employee;  
    4. import org.apache.ibatis.annotations.Select;  
    5.   
    6. import java.util.List;  
    7.   
    8. /** 
    9.  * Created by wanggenshen_sx on 2016/12/26. 
    10.  */  
    11.   
    12. public interface EmployeeMapper {  
    13.     @Select("select id,lastName,email from employee where id=#{id}")  
    14.     Employee getEmployeeById(int id);  
    15.   
    16.     @Select("select * from employee")  
    17.     List<Employee> getAllEmployees();  
    18. }  
    package com.mybatis.dao;

import com.mybatis.model.Employee;
import org.apache.ibatis.annotations.Select;

import java.util.List;

/**
 * Created by wanggenshen_sx on 2016/12/26.
 */

public interface EmployeeMapper {
	@Select("select id,lastName,email from employee where id=#{id}")
	Employee getEmployeeById(int id);

	@Select("select * from employee")
	List<Employee> getAllEmployees();
}

    2）实体类：Employee.java

    [java] view plain copy
     
    print?
    1. package com.mybatis.model;  
    2.   
    3. /** 
    4.  * Created by wanggenshen_sx on 2016/12/23. 
    5.  */  
    6. public class Employee {  
    7.   
    8.     private int id;  
    9.     private String lastName;  
    10.     private String email;  
    11.   
    12.     public int getId() {  
    13.         return id;  
    14.     }  
    15.     public void setId(int id) {  
    16.         this.id = id;  
    17.     }  
    18.     public String getLastName() {  
    19.         return lastName;  
    20.     }  
    21.     public void setLastName(String lastName) {  
    22.         this.lastName = lastName;  
    23.     }  
    24.     public String getEmail() {  
    25.         return email;  
    26.     }  
    27.     public void setEmail(String email) {  
    28.         this.email = email;  
    29.     }  
    30.     @Override  
    31.     public String toString() {  
    32.         return "Employee [id=" + id + ", lastName=" + lastName + ", email="  
    33.                 + email+" ]" ;  
    34.     }  
    35.     public Employee(){}  
    36. }  
    package com.mybatis.model;

/**
 * Created by wanggenshen_sx on 2016/12/23.
 */
public class Employee {

	private int id;
	private String lastName;
	private String email;

	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getLastName() {
		return lastName;
	}
	public void setLastName(String lastName) {
		this.lastName = lastName;
	}
	public String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}
	@Override
	public String toString() {
		return "Employee [id=" + id + ", lastName=" + lastName + ", email="
				+ email+" ]" ;
	}
	public Employee(){}
}

    3) Service层：

    创建EmployeeService接口

    [java] view plain copy
     
    print?
    1. package com.mybatis.service;  
    2.   
    3. import com.mybatis.model.Employee;  
    4.   
    5. import java.util.List;  
    6.   
    7. /** 
    8.  * Created by wanggenshen_sx on 2016/12/26. 
    9.  */  
    10. public interface EmployeeService {  
    11.     Employee getEmployee(int id);  
    12.   
    13.     List<Employee> getEmployees();  
    14. }  
    package com.mybatis.service;

import com.mybatis.model.Employee;

import java.util.List;

/**

 */
public interface EmployeeService {
	Employee getEmployee(int id);

	List<Employee> getEmployees();
}

    创建EmployeeServiceImpl实现类：注意添加@Service注解

    package com.mybatis.service;

import com.mybatis.dao.EmployeeMapper;
import com.mybatis.model.Employee;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

/**
 * Created by wanggenshen_sx on 2016/12/26.
 */
@Service
public class EmployeeServiceImpl implements EmployeeService {

   public EmployeeServiceImpl() {
      System.out.printf("init EmployeeServiceImpl");
   }

   @Autowired
   private EmployeeMapper employeeMapper;

   @Override
   public Employee getEmployee(int id){
      return employeeMapper.getEmployeeById(id);
   }

   public List<Employee> getEmployees(){
      return employeeMapper.getAllEmployees();
   }

}



    4）在spring配置文件中整合mybatis:spring-mybatis.xml

    <?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: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/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">

    <!--自动扫描含有@Service的类，将其注入为bean -->
    <context:component-scan base-package="com.mybatis.service" />
    <context:component-scan base-package="com.mybatis.dao" />

    <!-- 1. 数据源 : DriverManagerDataSource -->
    <bean id="datasource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3306/mytest"/>
        <property name="username" value="root"/>
        <property name="password" value="920614"/>
    </bean>

    <!--
        2. mybatis的SqlSession的工厂: SqlSessionFactoryBean
            dataSource / typeAliasesPackage
    -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="datasource"/>
        <property name="typeAliasesPackage" value="com.mybatis.model"/>
    </bean>

    <!--
        3. mybatis自动扫描加载Sql映射文件 : MapperScannerConfigurer
            sqlSessionFactory / basePackage
    -->
    <bean id="config" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
       <property name="basePackage" value="com.mybatis.dao"/>
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
    </bean>


    <!-- 4. 事务管理 : DataSourceTransactionManager -->
    <bean id="manager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="datasource"/>
    </bean>

    <!-- 5. 使用声明式事务 -->
    <tx:annotation-driven transaction-manager="manager" />

</beans>

    建测试类：EmployeeTest.java

    package com.mybatis.test;

import com.mybatis.model.Employee;
import com.mybatis.service.EmployeeService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import java.util.List;

/**
 * Created by wanggenshen_sx on 2016/12/27.
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:spring-mybatis.xml" })
public class EmployeeTest {

   @Autowired
   private EmployeeService employeeService;

   @Test
   public void testGetEmployeeById(){
      Employee employee = employeeService.getEmployee(1);
      System.out.print(employee);
   }

   @Test
   public void testGetAll(){
      List<Employee> employees=employeeService.getEmployees();
      System.out.print(employees);
   }
}

    能输出并显示数据库表的内容，即表示Spring整合Mybatis成功，接下来加入SpringMVC内容，将读取的内容显示在页面上。

    4 创建springmvc-servlet.xml,配置视图信息。

    <?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-4.0.xsd
      http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

    <!--注解-->
    <mvc:annotation-driven/>
    <!--处理静态资源-->
    <mvc:default-servlet-handler/>

    <!-- 自动扫描controller包下的有@Controller注解的，注入为bean -->
    <context:component-scan base-package="com.mybatis.controller" />

    <!--配置视图解析器-->
    <bean id="viewResolverCommon" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/"/>
        <property name="suffix" value=".jsp"/>
        <property name="viewClass"  value="org.springframework.web.servlet.view.JstlView" />
    </bean>


</beans>

    5 建控制类：
    EmployeeController.java

    package com.mybatis.controller;

import com.mybatis.model.Employee;
import com.mybatis.service.EmployeeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import java.util.List;
import java.util.Map;

/**
 * Created by wanggenshen_sx on 2016/12/26.
 */
@Controller
public class EmployeeController {

   @Autowired
   private EmployeeService employeeService;

   @RequestMapping(value=",Object> map){
      List<Employee> employees = employeeService.getEmployees();
       /*测试用
      if(employees==null)
         System.out.println("null");
      else
         System.out.println(employees);*/

      map.put("employees",employees);
      return "list";
   }


}

    6 建立显示页面: Web-app的WEB-INF下建views包下建list.jsp：

    注意此处一定要加上

    page false

    否则无法使用jstl标签。

    taglib chttp://java.sun.com/jsp/jstl/core" %>

<body>
                <table border="1" cellspacing="0" cellpadding="10">
                    <tr>
                        <th>ID</th>
                        <th>LastName</th>
                        <th>Email</th>
                    </tr>

                    c="}="emp">
                        <tr>
                            <th>}</th>
                            <th>}</th>
                            <th>}</th>
                        </tr>
                    c:forEach>
                </table>

</body>
</html>



    7 配置web.xml ,分别指定spring,springmvc配置文件的位置。注意这里一定要有四个部分，即<context-param>,<servlet>,<servlet-mapping>,<listener>.

      我在这里没有添加<listener>标签，spring无法初始化，出现了【Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'employeeController': Unsatisfied dependency expressed through field 'employeeService': No qualifying bean of type [com.mybatis.service.EmployeeService] found for dependency [com.mybatis.service.EmployeeService]: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: 】错误。
