创建并测试ssm项目

 源码：https://github.com/DevotedToAttack/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)

在resources文件夹下创建jdbcConfig.properties配置文件（为mybatis中的dataSource提供连接数据）

jdbc.driver=com.mysql.jdbc.Driver

jdbc.username=root
jdbc.password=12345678

在resources文件夹下创建springmvc.xml配置文件

在resources文件夹下创建log4j.properties配置文件（配置log4j日志格式）

#Set root category priority to INFO and its only appender to CONSOLE.
#log4j. rootCategory=INFO, CONSOLEdebug info warn error fatal
log4j.rootCategory=debug, CONSOLE, LOGFILE
# Set the enterprise logger category to FATAL and its only appender to CONSOLE.

log4j.appender.LOGFILE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n

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。
