配置连接属性

修改serviceImpl

package com.sd.test.service.impl;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.sd.test.dao.TTestMapper;

import com.sd.test.model.TTest;

import com.sd.test.service.TestService;

@Service

public class TestServiceImpl implements TestService {

    @Resource

    private TTestMapper mapper;

    @Override

    public void save(Object obj) {

        int i = this.mapper.insert((TTest) obj);

        System.out.println("save = " + i);

        System.out.println("save");

    }

    @Override

    public Object selectOne(Object obj) {

        System.out.println("selectOne");

        TTest tt = null;

        tt = this.mapper.selectByPrimaryKey(Integer.parseInt(obj.toString()));

        return tt;

    }

    @Override

    public Object put(Object obj) {

        System.out.println("put");

        return this.mapper.insert((TTest) obj);

    }

}

controller 代码如下:

package com.sd.test.controller;

import java.io.IOException;

import javax.annotation.Resource;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import com.sd.test.model.TTest;

import com.sd.test.service.TestService;

@Controller

@RequestMapping("/test")

public class TestController {

    @Resource

    private TestService testService;

    @RequestMapping("selectOne")

    public void findById(HttpServletRequest request,

            HttpServletResponse response) throws IOException {

        String id = request.getParameter("id");

        Object obj = this.testService.selectOne(Integer.parseInt(id));

        response.getWriter().print(obj);

    }

    @RequestMapping("save")

    public void save(HttpServletRequest request, HttpServletResponse response) {

        String name = request.getParameter("name");

        TTest t = new TTest();

        t.setUsername(name);

        this.testService.save(t);

    }

    @RequestMapping("tsave")

    public void tsave(HttpServletRequest request, HttpServletResponse response) {

        String name = request.getParameter("name");

        TTest t = new TTest();

        t.setUsername(name);

        int i = (Integer) this.testService.put(t);

        System.out.println(i);

    }

启动测试.

http://localhost:8080/prot/test/selectOne.do?id=1

页面上输出:

com.sd.test.model.TTest@9db6ecb

http://localhost:8080/prot/test/save.do?name=userNo1

控制台输出:

 save = 1

save
