SSM整合
一、前后端分离接口文档
SSMUSER服务器接口说明文档
服务器地址
http://localhost:8082
http://127.0.0.1:8082
数据接口说明
根据条件分页获取分页数据
url
- /user/selectUserPage?userName=z&userSex=男&page=null
参数
- userName:表单中用户名称
- userSex:表单中用户性别
- page:提交的页码(第一次访问为null)
结果
有数据时：
[{
"userId":"15968954638794962",
"cardType":"身份证","
cardNo":"343343554654",
"userName":"撒撒旦",
"userSex":"女",
"userAge":"29",
"userRole":"生产、运输设备操作人员及有关人员"},
{….}
]
无数据时：
[]
获取总行数
url
- /user/getRowCount?userName=z&userSex=男
参数
- userName:表单中用户名称
- userSex:表单中用户性别
结果
有数据时:
12
无数据时:
0
根据用户ID删除用户
url
- /user/ deleteUserById?userId= 15968162087363060
参数
- userId:删除用户的id
结果
删除成功时：
1
删除失败时:
0
增加用户
url
- /user/createUser(参数见下面)
参数
- cardType: this.ruleForm.cardType,//证件类型
- cardNo: this.ruleForm.cardNo,//证件号码
- userName: this.ruleForm.userName,//用户姓名
- userSex: this.ruleForm.userSex,//用户性别
- userAge: this.ruleForm.userAge,//用户年龄
- userRole: this.ruleForm.userRole,//用户角色
结果
增加成功时：
1
增加失败时:
0
二、SSM整合的步骤
0) 建库建表
SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;
CREATE DATABASE IF NOT EXISTS `ssmuser` DEFAULT CHARACTER SET utf8;
USE `ssmuser`;
-- ----------------------------
-- Table structure for user
-- ----------------------------
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (

PRIMARY KEY (`user_id`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = COMPACT;
-- ----------------------------
-- Records of user

SET FOREIGN_KEY_CHECKS = 1;
1) 新建Maven项目,选择webapp模板
2) 修改目录
3) 修改pom.xml文件

9) 新建web.xml文件
设置中文编码,并注册spirngmvc框架,并注册Spring框架
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"

<param-name>contextConfigLocation</param-name>
<!--使用通配符 注册两个配置文件-->
<param-value>classpath:applicationContext_*.xml</param-value>
</context-param>
</web-app>
10) 新建实体类user
package com.bjpowernode.pojo;
public class User {
private String userId;
private String cardType;
private String cardNo;
private String userName;
private String userSex;
private String userAge;
private String userRole;
@Override
public String toString() {
return "User{" +
"userId='" + userId + '\'' +

this.userName = userName;
this.userSex = userSex;
this.userAge = userAge;
this.userRole = userRole;
}
public User() {
}
}
11) 新建UserMapper.java接口
package com.bjpowernode.mapper;
import com.bjpowernode.pojo.User;
import org.apache.ibatis.annotations.Param;
import java.util.List;
/**
*
*/
public interface UserMapper {

String userName,
@Param("userSex")
String userSex);
}
12) 新建UserMapper.xml实现增删查功能
<?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">

13) 新建service接口和实现类
service接口
package com.bjpowernode.service;
import com.bjpowernode.pojo.User;
import java.util.List;
/**
*
*/
public interface UserService {
/**
* url /user/selectUserPage?userName=z&userSex=男&page=null
*/
List<User> selectUserPage(String userName,String userSex,int startRow);
/**
* /user/createUser(参数见下面)
*/
int createUser(User user);
/**
* user/ deleteUserById?userId= 15968162087363060
*/
int deleteUserById(String userId);
/**
* /user/getRowCount?userName=z&userSex=男
*/
int getRowCount(String userName,String userSex);
}
service实现类
package com.bjpowernode.service.impl;
import com.bjpowernode.mapper.UserMapper;
import com.bjpowernode.pojo.User;
import com.bjpowernode.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
/**
*
*/
@Service
public class UserServiceImpl implements UserService {
//切记切记:一定会有数据访问层的对象
@Autowired
UserMapper userMapper;
@Override
public List<User> selectUserPage(String userName, String userSex, int startRow) {
return userMapper.selectUserPage(userName,userSex,startRow);
}
@Override
public int createUser(User user) {
return userMapper.createUser(user);
}
@Override
public int deleteUserById(String userId) {
return userMapper.deleteUserById(userId);
}
@Override
public int getRowCount(String userName, String userSex) {
return userMapper.getRowCount(userName,userSex);
}
}
14) 新建测试类,完成所有功能的测试
package test;
import com.bjpowernode.pojo.User;
import com.bjpowernode.service.UserService;
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;
//Spring Test主要解决了以下问题：
//– 在普通测试环境下，当需要使用Spring时，需要手动加载Spring配置，且手动从 Spring容器中获取对象，使用Spring Test后，只需要通过注解指定Spring配置类， 在Spring容器中的对象均可自动装配
/**
*
*
*/
@RunWith(SpringJUnit4ClassRunner.class) //RunWith是一个运行器 让测试运行于Spring测试环境
@ContextConfiguration(locations = {"classpath:applicationContext_mapper.xml","classpath:applicationContext_service.xml"})
public class MyTest {
@Autowired
UserService userService;
@Test
public void testSelectUserPage(){
List<User> list = userService.selectUserPage("三","男",0);
list.forEach(user -> System.out.println(user));
}
@Test
public void testDeleteUserById(){
int num = userService.deleteUserById("15968162087363060");
System.out.println(num);
}
@Test
public void testGetRowCount(){
int num = userService.getRowCount(null,"男");
System.out.println(num);
}
@Test
public void testCreateUser(){
User u = new User("125412145214547846","身份证","121451245784","哈哈","男","23","工人");
int num = userService.createUser(u);
System.out.println("-----"+num);
}
}
15) 新建控制器,完成所有功能
package com.bjpowernode.controller;
import com.bjpowernode.pojo.User;
import com.bjpowernode.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import java.util.List;
/**
*
*/
@CrossOrigin //在服务器端支持跨域访问
@RestController //如果本类中全部都是ajax请求,则使用此注解,方法上的@ResponseBody可不写
@RequestMapping("/user")
public class UserController {
//切记切记:一定会有业务逻辑层的对象
@Autowired
UserService userService;
public static final int PAGE_SIZE = 5;
//user/selectUserPage?userName=z&userSex=男&page=null
@RequestMapping("/selectUserPage")
public List<User> selectUserPage(String userName,String userSex,Integer page){
//根据页码计算起始行
int startRow = 0;
if(page != null){
startRow = (page-1) * PAGE_SIZE;
}
return userService.selectUserPage(userName,userSex,startRow);
}
///user/getRowCount?userName=z&userSex=男
@RequestMapping("/getRowCount")
public int getRowCount(String userName,String userSex){
return userService.getRowCount(userName,userSex);
}
///user/deleteUserById?userId= 15968162087363060
@RequestMapping("/deleteUserById")
public int deleteUserById(String userId){
return userService.deleteUserById(userId);
}
///user/createUser(参数见下面)
@RequestMapping("/createUser")
public int createUser(User user){
String userId = System.currentTimeMillis()+"";
user.setUserId(userId);
return userService.createUser(user);
}
}
16) 浏览器测试功能
