Spring+SpringMvc+Mybatis项目搭建

Spring+SpringMvc+Mybatis项目搭建

一、新建maven项目

【1】新建project,选择Maven，快速创建选择web-app。

【2】填写project相关信息，next,next,finish,项目创建完成。

【3】建包建文件

二、引入项目需要的jar包，修改pom.xml文件

【1】pom.xml

三、配置WEB-INF下的web.xml

<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_3_0.xsd"
        id="WebApp_ID" version="3.0">

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

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

  servlet>
  <servlet-mapping>
    <servlet-name>springMvcservlet-name>
    <url-pattern>/url-pattern>
  servlet-mapping>
web-app>

四、配置springMvc.xml

<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"
       xsi:schemaLocation=" http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
       http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context-3.0.xsd
       http://www.springframework.org/schema/aop
       http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
       http://www.springframework.org/schema/tx
       http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">

    
    <context:component-scan base-package="com.mage.controller" />
    
    <mvc:annotation-driven />
    
    <bean id="defaultViewResolver"
          class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
        <property name="contentType" value="text/html" />
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    bean>
    
    <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping">
    bean>
    <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
        <property name="messageConverters">
            <list>
                <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter" />
            list>
        property>
    bean>
    
    <bean id="multipartResolver"

        <property name="maxUploadSize">
            <value>104857600value>
        property>
        <property name="maxInMemorySize">
            <value>4096value>
        property>
    bean>
beans>

五、配置spring.xml

<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:aop="http://www.springframework.org/schema/aop"
       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/aop
       http://www.springframework.org/schema/aop/spring-aop.xsd
       http://www.springframework.org/schema/tx
       http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">
    
    <context:component-scan base-package="com.mage" >
        <context:exclude-filter type="annotation"
                                expression="org.springframework.stereotype.Controller" />
    context:component-scan>
    
    <context:property-placeholder location="classpath:db.properties" />
    <aop:aspectj-autoproxy />
    
    
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driver}">property>
        <property name="jdbcUrl" value="${jdbc.url}">property>
        <property name="user" value="${jdbc.user}">property>
        <property name="password" value="${jdbc.password}">property>
    bean>

    
    <bean id="txManager"
          class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource">property>
    bean>
    
    <tx:advice id="txAdvice" transaction-manager="txManager">
        <tx:attributes>
            <tx:method name="get*" read-only="true" />
            <tx:method name="find*" read-only="true" />
            <tx:method name="query*" read-only="true" />
            <tx:method name="load*" read-only="true" />
            <tx:method name="add*" propagation="REQUIRED" />
            <tx:method name="insert*" propagation="REQUIRED" />
            <tx:method name="update*" propagation="REQUIRED" />
            <tx:method name="delete*" propagation="REQUIRED" />
        tx:attributes>
    tx:advice>

    <aop:config>
        <aop:pointcut id="servicePointcut" expression="execution(* com.mage.service..*.*(..))" />
        <aop:advisor advice-ref="txAdvice" pointcut-ref="servicePointcut" />
    aop:config>
    
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource">property>
        <property name="configLocation" value="classpath:mybatis.xml" />
        <property name="mapperLocations" value="classpath:com/mage/mapper/*.xml" />
    bean>
    
    <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        
        <property name="basePackage" value="com.mage.dao" />
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
    bean>
beans>

六、db.properties文件

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/crm?useUnicode=true&characterEncoding=utf8
jdbc.user=root
jdbc.password=123456

七、mybatis.xml配置

<configuration>
    
    <typeAliases>
        <package name="com.mage.pojo">package>
    typeAliases>
configuration>

八、添加tomcat服务器

【1】点击下图按钮

【2】添加tomcat服务器，并将项目添加进去

九、测试

UserController:

package com.mage.controller;

import com.mage.pojo.User;
import com.mage.service.UserService;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import javax.annotation.Resource;

@Controller
public class UserController {
    @Resource
    private UserService userService;

    @RequestMapping("/queryUser")
    @ResponseBody
    public User queryUserById(Integer id){
        return userService.queryUserById(id);
    }
}

UserDao:

package com.mage.dao;

import com.mage.pojo.User;

public interface UserDao {
    /*
    根据id查找用户
     */
    public User queryUserById(Integer id);
}

mapper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.mage.dao.UserDao">
    <select id="queryUserById" parameterType="int" resultType="user">
        SELECT id,user_name 'userName',true_name 'trueName'
        FROM t_user WHERE id = #{id}
    </select>
</mapper>

User实体类

package com.mage.pojo;

public class User {
    private Integer id;
    private String userName;
    private String trueName;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getTrueName() {
        return trueName;
    }

    public void setTrueName(String trueName) {
        this.trueName = trueName;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", userName='" + userName + '\'' +
                ", trueName='" + trueName + '\'' +
                '}';
    }
}

UserService

package com.mage.service;

import com.mage.dao.UserDao;
import com.mage.pojo.User;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;

@Service
public class UserService {
    @Resource
    private UserDao userDao;

    public User queryUserById(Integer id){
        return userDao.queryUserById(id);
    }

}

启动服务器

结果：

OK，没有问题，框架搭建完成
