SSM整合

项目源码：https://github.com/zhongyushi-git/spring-collection.git。下载代码后，示例代码在ssmSystem文件夹下。 

1.创建项目

1.1新建一个maven的web项目

 点击下一步，填写相关信息。

1.2添加java和resources目录

在main目录下新建java目录和resources目录，并把他们设置为资源目录

2.在pom.xml导入依赖

<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>
    <mvc:default-servlet-handler/>

6.配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">

    <welcome-file-list>
        <welcome-file>login.html</welcome-file>
    </welcome-file-list>

    <!--设置编码，处理乱码-->
    <filter>
        <filter-name>charsetEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>CharsetEncoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <!--拦截所有的请求-->
    <filter-mapping>
        <filter-name>charsetEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!--启动spring容器-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring/applicationContext-*.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!--springmvc前端控制器-->
    <servlet>
        <servlet-name>DispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!--加载配置文件-->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring/springmvc.xml</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>DispatcherServlet</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>

</web-app>

7.mapper文件的配置

在resourcesm目录下创建mapper文件夹，所有的mapper.xml文件将放在这里。

8.添加tomcat服务器

前提是本地已安装tomcat server，若没有请先安装。

8.1选择环境配置

8.2选择tomcat服务器

8.3点击+号选择本地的tomcat server

8.4选择要启动的项目类型

 

8.5选择启动的项目

选择后一般会带项目名加war进行访问，可以直接修改为项目名

8.6选择tomcat服务器

 然后点击确定即可。后面直接运行这个服务就能够访问资源。

9.在webapp下新建页面

新建login.html和view/index.html，还需要加入bootstrap的文件，详见源码。

10.数据库执行脚本

create database db2020;
use db2020;

CREATE TABLE `user`  (
  `id` varchar(200) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT 'id',
  `name` varchar(200) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT '' COMMENT '姓名',
  `phone` varchar(200) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT '' COMMENT '电话',
  `password` varchar(200) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '密码',
  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Compact;

INSERT INTO `user` VALUES ('admin', '曾漫华', '123444', '123444');
INSERT INTO `user` VALUES ('likai', '李凯1', '1234', '123');
INSERT INTO `user` VALUES ('liming', '李明', '101', '12345');
INSERT INTO `user` VALUES ('lisi', '李四', '111', '111');
INSERT INTO `user` VALUES ('wangwu', '王五', '1111', '1111');
INSERT INTO `user` VALUES ('xixixi', '嘻嘻嘻', '1134444', '12345');
INSERT INTO `user` VALUES ('zhangmin', '张敏', '123', '123');
INSERT INTO `user` VALUES ('zhangsan', '张三', '112', '112');

 数据库执行完成后启动项目，访问http://localhost:8080/ssmSystem/login.html使用正确的用户名和密码即可登录，登录后会跳转到首页，对用户的信息进行基本的增删改查。
