6-ssm整合-原始整合方式-逻辑代码编写

接续上篇，接下来需要将AccountService的具体实现写出来，如D:\os\SpringWebApp\SpringProject2Module10SSM\src\main\java\sp10\service\impl\AccountServiceImpl.java:
package sp10.service.impl;

import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.springframework.stereotype.Service;
import sp10.domain.Account;
import sp10.mapper.AccountMapper;
import sp10.service.AccountService;

import java.io.IOException;
import java.io.InputStream;
import java.util.List;
@Service("accountService")
public class AccountServiceImpl implements AccountService {
    @Override
    public void save(Account account) {
        try {
            InputStream resourceAsStream = Resources.getResourceAsStream("sqlMapConfig.xml");
            SqlSessionFactory sqlSessionFactory=new SqlSessionFactoryBuilder().build(resourceAsStream);
            SqlSession sqlSession=sqlSessionFactory.openSession();
            AccountMapper mapper=sqlSession.getMapper(AccountMapper.class);
            mapper.save(account);
            sqlSession.commit();
            sqlSession.close();
        } catch (IOException e) {
            e.printStackTrace();
        }

    }

    @Override
    public List<Account> findAll() {
        try {
            InputStream resourceAsStream = Resources.getResourceAsStream("sqlMapConfig.xml");
            SqlSessionFactory sqlSessionFactory=new SqlSessionFactoryBuilder().build(resourceAsStream);
            SqlSession sqlSession=sqlSessionFactory.openSession();
            AccountMapper mapper=sqlSession.getMapper(AccountMapper.class);
            List<Account> accountList = mapper.findAll();
            sqlSession.close();
            return accountList;
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }
}
然后接下来是controller的完善，如D:\os\SpringWebApp\SpringProject2Module10SSM\src\main\java\sp10\controller\AccountController.java:
package sp10.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;
import sp10.domain.Account;
import sp10.service.AccountService;

import java.util.List;

@Controller
@RequestMapping("/account")
public class AccountController {
    @Autowired
    /*
    通过@Autowired注解，自动注入AccountService接口的实现类
    实现类中必须有Service注解标明为accountService
    */
    private AccountService accountService;
    //保存
    @RequestMapping("/save")
    @ResponseBody
    public String save(Account account){
        accountService.save(account);
        return "保存成功";
    }
    //查询
    public ModelAndView findAll(){
        List<Account> accountList=accountService.findAll();
        ModelAndView modelAndView=new ModelAndView();
        modelAndView.addObject("accountList",accountList);
        modelAndView.setViewName("accountList");
        return modelAndView;
    }
}
