Spring + SpringMvc + Mybatis 搭建SSM框架

在闲暇之余，又开始玩玩javaEE的东西，不然都要忘记了。初步打算做一个开源的CMS，今天先搭建起框架，提交github后续完善，需要的可以看看，fork下，顺便给个star吧。

什么是SSM?

SSM对应 spring springmvc mybatis
springmvc 采用MVC模式，主要是作用于用户交互
spring 采用IOC和AOP~作用比较抽象，是用于项目的松耦合
mybatis 是对象持久化框架，其实就是实体类和数据库表建立关系，通过mapper.xml文件写sql语句，完成数据库编程
SSM就是Spring + SpringMvc + Mybatis 3个Java框架的集合，现在Java开发中常用的框架组合。用来开发后台，与前台和数据库进行数据交互.

环境准备

jdk1.8 :java运行环境

mysql: 数据库

IDE: 代码编辑工具

MAVEN: 项目管理工具

开始搭建

新建maven项目

2种方式：IDE和mvn ，具体自己弄。
以下是结构截图，src和pom.xml必须

添加依赖

下面是常用的javaEE开发包的版本

搭建springMvc

打开webapp/WEB-INF/web.xml文件，添加请求映射器，添加如下：

  
    <filter>
        <filter-name>encodingFilterfilter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>
        <init-param>
            <param-name>encodingparam-name>
            <param-value>UTF-8param-value>
        init-param>
    filter>
    <filter-mapping>
        <filter-name>encodingFilterfilter-name>
        <url-pattern>/*url-pattern>
    filter-mapping>

    
    <servlet>
        <servlet-name>SpringMVCservlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
        <init-param>
            <description>SpringMVCdescription>
            <param-name>contextConfigLocationparam-name>
            <param-value>classpath:spring-mvc.xmlparam-value>
        init-param>
        <load-on-startup>1load-on-startup>
    servlet>
    <servlet-mapping>
        <servlet-name>SpringMVCservlet-name>
        <url-pattern>/url-pattern>
    servlet-mapping>

我们可以看到上面的代码中有classpath:spring-mvc.xml代码，所以在resources目录下添加spring-mvc.xml文件。然后打开编辑：

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

    <description>spring mvcdescription>
    <context:component-scan base-package="cn.yjxxclub.shijie" use-default-filters="false">
       
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    context:component-scan>

    <mvc:default-servlet-handler/>
    <mvc:annotation-driven/>
    
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/page/">property>
        <property name="suffix" value=".jsp">property>
    bean>

    <bean id="multipartResolver"
          class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <property name="defaultEncoding" value="UTF-8"/>
        <property name="maxUploadSize" value="10000000"/>
    bean>
    
    <bean id="mappingJackson2HttpMessageConverter"
          class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
                <value>text/html;charset=UTF-8value>
                <value>text/json;charset=UTF-8value>
                <value>application/json;charset=UTF-8value>

    <bean
            class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
        <property name="messageConverters">
            <list>
                <ref bean="mappingJackson2HttpMessageConverter"/>    
            list>
        property>
    bean>
    
    

beans>

xml文件配置基本完成，下面就是java代码了：

/**
 * Author: tengxing
 * Email: [email protected]
 * Date: 17-3-15
 * Time: 下午6:16
 * Describe: 测试
 */
@RestController
@RequestMapping("/test")
public class TestController extends BaseController{
    @RequestMapping(value = "hello", method = RequestMethod.GET)
    public Object hello(){
        System.out.println("--exe--");
        return renderSuccess("hello world");
    }

}
protected JsonResult renderSuccess(String msg) {
        JsonResult result = renderSuccess();
        result.setMsg(msg);
        return result;
    }

打开浏览器：

至此springmvc搭建完毕。
