1、整体思想

用spring整合mybatis和springmvc,每搭建完一个就测试一个

一个简单的ssm整合案例之搭建spring环境_spring配置

2、pom.xml

3、完成此目录结构

一个简单的ssm整合案例之搭建spring环境_spring_02

4、domain层  ----Account.java

package com.cnstrong.domain;

import java.io.Serializable;

/*
 *账户
 */
public class Account implements Serializable {
    private Integer id;
    private String name;
    private Double 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;
    }
}

5、dao层---AccountDao

package com.cnstrong.dao;

import com.cnstrong.domain.Account;

import java.util.List;

/**
 * 账户Dao接口
 */
public interface AccountDao {

    //查询所有账户信息
    public List<Account> findAll();

    //保存账户信息
    public void saveAccount(Account account);

}

6、service层---AccountService

package com.cnstrong.service;

import com.cnstrong.domain.Account;

import java.util.List;

public interface AccountService {

    //查询所有账户信息
    public List<Account> findAll();

    //保存账户信息
    public void saveAccount(Account account);

}

7、service.impl层--AccountServiceImpl

package com.cnstrong.service.impl;

import com.cnstrong.domain.Account;
import com.cnstrong.service.AccountService;
import org.springframework.stereotype.Service;

import java.util.List;
@Service("accountService")
public class AccountServiceImpl implements AccountService {

    @Override
    public List<Account> findAll() {
        System.out.println("业务层,查询所有账户...");
        return null;
    }

    @Override
    public void saveAccount(Account account) {
        System.out.println("业务层,保存账户...");
    }
}

8、resources下的applicationContext.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>
<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:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="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.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx.xsd">

    
    <!--开启注解的扫描,希望处理servicce和dao,controller不需要spring框架去处理-->
    <context:component-scan base-package="com.cnstrong">
        <!--配置哪些注解不扫描-->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" />
    </context:component-scan>
</beans>

9、TestSpring单元测试类

package com.cnstrong.test;

import com.cnstrong.service.AccountService;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestSpring {
    @Test
    public void run1(){
        //加载配置文件
        ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
        //获取对象
        AccountService as= (AccountService) ac.getBean("accountService");
        //调用方法
        as.findAll();
    }
}
