尚硅谷SSM框架——SSM实战演练学习笔记
一、搭建maven工程
1.1、补齐目录
先项目上右键，选择属性
先去掉，然后再勾上下图选项
1.2、配置生成的web.xml的位置
二、 通过pom.xml引进相关jar依赖
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

三、 引进bootstrap和jQuery
https://v3.bootcss.com/
3.1、使用bootstrap
引入基本样式css和JavaScript和jQuery
使用
四、配置相关xml文件
4.1、配置web.xml
<web-app id="WebApp_ID" version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://JAVA.sun.com/xml/ns/javaee

servlet-name标签出错的解决方案
4.2、配置spring的配置文件applicationContext.xml
<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:aop="http://www.springframework.org/schema/aop"

<tx:attributes>
<tx:method name="*"/>
<tx:method name="get*" read-only="true"/>
tx:attributes>
tx:advice>
beans>
4.3、配置springmvc的配置文件springmvc.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:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
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-4.3.xsd">
<context:component-scan base-package="com.atguigu" use-default-filters="false">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
context:component-scan>
<bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/">property>
<property name="suffix" value=".jsp">property>
bean>
<mvc:default-servlet-handler/>
<mvc:annotation-driven>mvc:annotation-driven>
beans>
4.4、配置数据库连接文件db.properties
jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm_crud?serverTimezone=Hongkong
jdbc.username=root
jdbc.password=75688
4.5、mybatis-config.xml配置
<configuration>
<settings>
<setting name="mapUnderscoreToCamelCase" value="true"/>
settings>
<typeAliases>
<package name="com.atguigu.crud.bean">package>
typeAliases>
configuration>
五、创建数据库表
六、mybatis逆向工程
6.1、引入mabatis逆向工程所需依赖
6.2、mbg.xml
参考http://mybatis.org/generator/
<generatorConfiguration>
<context id="DB2Tables" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressAllComments" value="true"/>
commentGenerator>
<jdbcConnection
driverClass="com.mysql.cj.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/ssm_crud?serverTimezone=Hongkong"
userId="root"
password="75688">
jdbcConnection>
<javaTypeResolver >
<property name="forceBigDecimals" value="false" />
javaTypeResolver>
<javaModelGenerator
targetProject=".\src\main\java"
targetPackage="com.atguigu.crud.bean" >
<property name="enableSubPackages" value="true" />
<property name="trimStrings" value="true" />
javaModelGenerator>
<sqlMapGenerator
targetProject=".\src\main\resources"
targetPackage="mapper">
<property name="enableSubPackages" value="true" />
sqlMapGenerator>
<javaClientGenerator type="XMLMAPPER"
targetProject=".\src\main\java"
targetPackage="com.atguigu.crud.dao">
<property name="enableSubPackages" value="true" />
javaClientGenerator>
<table tableName="tbl_emp" domainObjectName="Employee">table>
<table tableName="tbl_dept" domainObjectName="Department">table>
context>
generatorConfiguration>
6.3、使用逆向工程生成代码
参考官方文档
6.3.1、MBGTest.java
package com.atguigu.crud.test;
import java.io.File;
import java.util.ArrayList;
import java.util.List;
import org.mybatis.generator.api.MyBatisGenerator;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.exception.XMLParserException;
import org.mybatis.generator.internal.DefaultShellCallback;
public class MBGTest {
public static void main(String[] args) throws Exception, XMLParserException {
System.out.println("============开始执行逆向工程============");
List<String> warnings = new ArrayList<String>();
boolean overwrite = true;
File configFile = new File("mbg.xml");
ConfigurationParser cp = new ConfigurationParser(warnings);
Configuration config = cp.parseConfiguration(configFile);
DefaultShellCallback callback = new DefaultShellCallback(overwrite);
MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
myBatisGenerator.generate(null);
System.out.println("============执行逆向工程结束============");
}
}
运行上面代码将自动生成逆向工程
七、自定义SQL查询
7.1、新增查询1
查询结果封装
7.2、新增查询2
八、使用spring单元测试
8.1、简单插入
@RunWith(SpringJUnit4ClassRunner.class)//使用Springtest测试框架
@ContextConfiguration(locations= {"classpath:applicationContext.xml"})
public class MapperTest {
@Autowired
DepartmentMapper departmentMapper ;
@Autowired
EmployeeMapper employeeMapper;
@Test
public void testCRUD() {
//1、部门插入测试
//departmentMapper.insertSelective(new Department(null,"销售部"));
//2、员工插入测试
employeeMapper.insertSelective(new Employee(null,"苗丹","M","[email protected]",1));
}
}
8.2、批量插入
@RunWith(SpringJUnit4ClassRunner.class)//使用Springtest测试框架
@ContextConfiguration(locations= {"classpath:applicationContext.xml"})
public class MapperTest {
@Autowired
EmployeeMapper employeeMapper;
@Autowired
SqlSession sqlSession;
@Test
public void testCRUD() {
//批量插入员工数据
EmployeeMapper mapper = sqlSession.getMapper(EmployeeMapper.class);
for(int i=0;i<968;i++){
String uid= UUID.randomUUID().toString().toString().substring(0,5)+i;
mapper.insertSelective(new Employee(null, uid, "M", uid+"@qq.com", 1));
}
System.out.println("============批量插入员工数据完成============");
}
}
九、PageHelper分页插件的使用
9.1、引进PageHelper maven依赖
9.2、在mybatis-config.xml注册PageHelper分页插件
十、查询功能
controller处理请求
Service执行业务逻辑
分页查询的单元测试
//使用Spring测试模块提供的测试请求功能，测试curd请求的正确性
@RunWith(SpringJUnit4ClassRunner.class)//使用Springtest测i试框架
@ContextConfiguration(locations = {"classpath:applicationContext.xml","classpath:springmvc.xml"})
@WebAppConfiguration
public class MvcTest {
//传入Springmvc的ioc
@Autowired
WebApplicationContext context;
//虚拟mvc请求，获取到处理结果。
MockMvc mockMvc ;
@Before
public void initMokcMvc(){
mockMvc = MockMvcBuilders.webAppContextSetup(context).build();
}
@Test
public void testPage() throws Exception {
//模拟发送请求，获取第5页数据，得到返回值
MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.get("/emps").param("pn","5"))
.andReturn();
//请求成功以后 请求域中有pageINfo；我们可以取出来pageInfo进行验证
MockHttpServletRequest request = mvcResult.getRequest();
PageInfo pageInfo = (PageInfo) request.getAttribute("pageInfo");
//进行输出
System.out.println("当前页码："+pageInfo.getPageNum());
System.out.println("总页码："+pageInfo.getPages());
System.out.println("总记录数："+pageInfo.getTotal());
int[] nums = pageInfo.getNavigatepageNums();
System.out.println("在页面需要连续显示的页码：");
for (int i:nums ) {
System. out.print(" "+i);
}
System. out.println("");
//也获取员工数据
List<Employee> list = pageInfo.getList();
for (Employee employee : list) {
System.out.println("ID: "+employee.getEmpId( )+"== >Name："+employee.getEmpName());
}
}
}
10.1、前端页面设计
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<html>
<head>
<meta charset="UTF-8">

<%
pageContext.setAttribute("APP_PATH", request.getContextPath());
%>

10.2、返回json数据
准备通用的返回类
package com.atguigu.crud.bean;
import java.util.HashMap;
import java.util.Map;
/**
* 通用的返回类
*/
public class Msg {
//状态码 100-success 200-fail
private int code;
//提示信息
private String msg;
//用户返回给浏览器的数据
private Map<String, Object> extend = new HashMap<String, Object>();
/*================自定义方法开始=======================*/
public static Msg success() {
Msg msg = new Msg();
msg.setCode(100);
msg.setMsg("处理成功!");
return msg;
}
public static Msg fail() {
Msg msg = new Msg();
msg.setCode(200);
msg.setMsg("处理失败!");
return msg;
}
public Msg add(String key,Object value) {
this.getExtend().put(key, value);
return this;
}
/*================自定义方法结束=======================*/
public int getCode() {
return code;
}
public void setCode(int code) {
this.code = code;
}
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}
public Map<String, Object> getExtend() {
return extend;
}
public void setExtend(Map<String, Object> extend) {
this.extend = extend;
}
}
10.3、使用ajax

10.3.3、jQuery添加样式和标签属性
10.3.4、jQuery将新增控件添加到页面语法

十二、编辑功能
jQuery按钮点击事件
十三、删除功能
十四、jsp完整代码
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
