package com.service;
import com.pojo.Paper;
import java.util.List;
public interface PaperService {
int addPaper(Paper paper);
int deletePaperById(long id);
int updatePaper(Paper paper);
Paper queryById(long id);
List queryAllPaper();
}
在service包下新建impl包，并在此包中新建PaperServiceImpl.java
package com.service.impl;
import com.pojo.Paper;
import com.dao.PaperDao;
import com.service.PaperService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class PaperServiceImpl implements PaperService {
@Autowired
private PaperDao paperDao;
@Override
public int addPaper(Paper paper) {
return paperDao.addPaper(paper);
}
@Override
public int deletePaperById(long id) {
return paperDao.deletePaperById(id);
}
@Override
public int updatePaper(Paper paper) {
return paperDao.updatePaper(paper);
}
@Override
public Paper queryById(long id) {
return paperDao.queryById(id);
}
@Override
public List queryAllPaper() {
return paperDao.queryAllPaper();
}
}
在dao包中新建接口 PaperDao.java
package com.dao;
import com.pojo.Paper;
import java.util.List;
public interface PaperDao {
int addPaper(Paper paper);
int deletePaperById(long id);
int updatePaper(Paper paper);
Paper queryById(long id);
List queryAllPaper();
}
在controller包中新建 PaperController.java
package com.controller;
import com.pojo.Paper;
import com.service.PaperService;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("/paper")
public class PaperController {
@Autowired
private PaperService paperService;
@RequestMapping("/allPaper")
public String list(Model model) {
List list = paperService.queryAllPaper();
model.addAttribute("list", list);
return "allPaper";
}
@RequestMapping("toAddPaper")
public String toAddPaper() {
return "addPaper";
}
@RequestMapping("/addPaper")
public String addPaper(Paper paper) {
paperService.addPaper(paper);
return "redirect:/paper/allPaper";
}
@RequestMapping("/del/{paperId}")
public String deletePaper(@PathVariable("paperId") Long id) {
paperService.deletePaperById(id);
return "redirect:/paper/allPaper";
}
@RequestMapping("toUpdatePaper")
public String toUpdatePaper(Model model, Long id) {
model.addAttribute("paper", paperService.queryById(id));
return "updatePaper";
}
@RequestMapping("/updatePaper")
public String updatePaper(Model model, Paper paper) {
paperService.updatePaper(paper);
paper = paperService.queryById(paper.getPaperId());
model.addAttribute("paper", paper);
return "redirect:/paper/allPaper";
}
}
INSERT INTO paper(paper_id,name,number,detail) VALUE (#{paperId},#{paperName}, #{paperNum}, #{paperDetail})
DELETE FROM paper WHERE paper_id=#{paperID}
UPDATE paper
SET NAME = #{paperName},NUMBER = #{paperNum},detail = #{paperDetail}
WHERE paper_id = #{paperId}

Log4j组件：Logger、Appender、Layout
Log4j核心包含三个组件：logger、appender和layout。这三个组件协作提供日志功能：
日志的输出目标
日志的输出格式
日志的输出级别(是否抑制日志的输出)
logger继承特性
A logger is said to be an ancestor of anothe

对于那些具有强迫症的工程师来说，软件汉化固然好用，但是汉化不完整却极为头疼，本方法针对iReport汉化不完整的情况，强制使用英文版，方法如下：
在 iReport 安装路径下的 etc/ireport.conf 里增加红色部分启动参数，即可变为英文版。

网上找了很久，都是用Gallery实现的，效果不是很满意，结果发现这个用OpenGL实现的，稍微修改了一下源码，实现了无限循环功能
