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
