项目源码:https://gitee.com/wu_xu_bin/newssm
第一步、新建一个有webapp框架的maven项目
点击新建项目选择sdk版本,选中Maven勾选添加框架,选中maven下的webapp框架,点击下一步
填写路径和工程名字,点击下一步
为了加快ssm工程的创建可以手动添加一对Property
Name为archetypeCatalog
Value为internal
添加之后可以提升2~3倍的创建速度
选择Maven版本,点击下一步
填写项目名和项目存储路径,点击完成
第二步、创建相关文件夹
创建在mian文件夹下创建java和resources文件夹
然后设置java为Sources Root
然后设置resources为Resources Root
完成后结果如图
第三步、配置pom.xml、web.xml、applicationContext.xml、springmvc.xml、jdbcConfig.properties、log4j.properties文件
先在pom.xml文件导入相关依赖(对应的依赖都有注释)

至此一个ssm项目已经创建完成。
第四步、编写测试类
接下来通过编写测试类来测试ssm项目是否可以运行。
先在java文件夹下创建如下包
然后在controller包下创建AccountController.java类
并写入如下测试代码:
package cn.controller;
import cn.domain.Account;
import cn.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.List;
@Controller
@RequestMapping("/account")
public class AccountController {
@Autowired
private AccountService accountService;
@RequestMapping("/findAll")
public ModelAndView findAll(){
System.out.println("表现层,查询所有账户...");
ModelAndView mv=new ModelAndView();
//调用service的方法
List<Account> accounts=accountService.findAll();
mv.addObject("accounts",accounts);
mv.setViewName("account-list");
return mv;
}
@RequestMapping("/save")
public String save(Account account, HttpServletRequest request, HttpServletResponse response) throws IOException {
System.out.println("表现层,保存账户...");
accountService.saveAccount(account);
return "redirect:findAll";
}
}
在domain包下创建单元对象Account,代码如下
package cn.domain;
import java.io.Serializable;
public class Account implements Serializable {
private Integer id;
private String name;
private Double money;
@Override
public String toString() {
return "Account{" +
"id=" + id +
", name='" + name + '\'' +
", money=" + money +
'}';
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Double getMoney() {
return money;
}
public void setMoney(Double money) {
this.money = money;
}
}
在service包下创建AccountService接口,并在该包下创建一个impl包可供存放service包下的接口实现类
AccountService接口,代码入下:
package cn.service;
import cn.domain.Account;
import org.springframework.stereotype.Service;
import java.util.List;
public interface AccountService {
//查询所有账户
public List<Account> findAll();
//保存账户信息
public void saveAccount(Account account);
}
impl包下的AccountService接口的实现类AccountServiceImpl代码如下
package cn.service.impl;
import cn.dao.AccountDao;
import cn.domain.Account;
import cn.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service("accountService")
public class AccountServiceImpl implements AccountService {
@Autowired
private AccountDao accountDao;
@Override
public List<Account> findAll() {
System.out.println("业务层:查询所有账户");
return accountDao.findAll();
}
@Override
public void saveAccount(Account account) {
System.out.println("业务层:保存账户");
accountDao.saveAccount(account);
}
}
在dao包下创建AccountDao持久层接口,详细代码如下
package cn.dao;
import cn.domain.Account;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;
import java.util.List;
@Repository
public interface AccountDao {
//查询所有账户
@Select("select * from account")
public List<Account> findAll();
//保存账户信息
@Insert("insert into account (name,money) values(#{name},#{money})")
public void saveAccount(Account account);
}
这是accoun表t的建表语句
create table account(
id int not null primary key AUTO_INCREMENT,
name varchar(32),
money double
)
在test包下编写测试类TestSpring.java,测试service层中的findAll方法,代码如下
package cn.test;
import cn.domain.Account;
import cn.service.AccountService;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import java.util.List;
public class TestSpring {
private ApplicationContext ac;
@Before
public void init(){
ac=new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
}
@After
public void closesql(){
}
@Test
public void testFindAll(){
AccountService as=(AccountService) ac.getBean("accountService");
List<Account> accounts=as.findAll();
for (Account account:accounts) {
System.out.println(account);
}
}
}
右键选择testFindAll方法,运行此方法,若是运行结果如下
则说明service层的findAll方法没有问题
接下来编写index.jsp测试页面,代码如下
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false"%>
<html>
<body>
<a href="${pageContext.request.contextPath}/account/findAll">查询全部</a><br>
<form action="${pageContext.request.contextPath}/account/save" method="post">
name:<input name="name" type="text"/><br>
money:<input name="money" type="text"/>(只允许输入数字)<br>
<button type="submit" value="提交">提交</button>
</form>
</body>
</html>
然后在webapp的pages包下创建一个显示表数据的account-list.jsp页面,代码如下
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false"%>
<html>
<head>
<title>Title</title>
</head>
<body>
<table>
<tr>
<th>id</th>
<th>name</th>
<th>money</th>
</tr>
<c:forEach items="${accounts}" var="account">
<tr>
<td>${account.id}</td>
<td>${account.name}</td>
<td>${account.money}</td>
</tr>
</c:forEach>
</table>
</body>
</html>
至此ssm项目的测试测试部分就创建好了
最后将ssm部署到tomcat上,详细步骤如下图
至此运行项目
出现index页面,如下图
点击查询全部,如下图
然后填写表单并提交页面自动转跳至account-list页面,如下图
到此ssm项目创建并测试成功,结束。
