使用分页插件(pagehelper)显示日志

sm(noSpringMVC)

1. spring+mybatis+pagehelper+ajax(noSpringMVC) 分页显示日志信息（传参(无法排序)、调用静态方法(startPage()) 两种的方式）

1. 数据准备、导入jar、web.xml、spring配置文件(applicationContext.xml)

数据准备：登录注册项目的操作日志表log

CREATE TABLE `log` (
 `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '编号',
 `pageinfo` varchar(50) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '用户操作信息',
 `ip` int(10) unsigned DEFAULT NULL COMMENT 'ip信息',
 `time` datetime DEFAULT NULL COMMENT '操作时间',
 PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=150 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci;

导入jar包:
jar01 jar02

2.pojo

Log.java

package com.zy.pojo;

public class Log {
	int id;
	String pageInfo;
	String ip;
	String time;
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getPageInfo() {
		return pageInfo;
	}
	public void setPageInfo(String pageInfo) {
		this.pageInfo = pageInfo;
	}
	public String getIp() {
		return ip;
	}
	public void setIp(String ip) {
		this.ip = ip;
	}
	public String getTime() {
		return time;
	}
	public void setTime(String time) {
		this.time = time;
	}
	@Override
	public String toString() {
		return "Log [id=" + id + ", pageInfo=" + pageInfo + ", ip=" + ip + ", time=" + time + "]";
	}
}

3.持久层mapper

LogMapper.java

package com.zy.mapper;
import java.util.List;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;
import com.zy.pojo.Log;
public interface LogMapper {
	/**
	 * 使用调用静态方法的方式
	 * @return
	 */
	@Select("select * from log")
	List<Log> selByPageStatic();
	/**
	 * 使用传参的方式
	 * @param pageNum
	 * @param pageSize
	 * @return
	 */
	@Select("select * from log")
	List<Log> selByPage(
			@Param("pageNum") int pageNum,
			@Param("pageSize") int pageSize);
}

4.业务层service

LogService.java

package com.zy.service;
import com.github.pagehelper.PageInfo;
import com.zy.pojo.Log;
public interface LogService {
	/**
	 * 通过调用静态方法的方式
	 * @return
	 */
	PageInfo<Log> showLog();
	/**
	 * 通过传参的方式
	 * @param pageNumStr
	 * @param pageSizeStr
	 * @return
	 */
	PageInfo<Log> showLog(int pageNum ,int pageSize );
}

LogServiceImpl.java

package com.zy.service.impl;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import com.github.pagehelper.PageInfo;
import com.zy.mapper.LogMapper;
import com.zy.pojo.Log;
import com.zy.service.LogService;

@Service
public class LogServiceImpl implements LogService{
	@Resource
	private LogMapper mapper;
	@Override
	public PageInfo<Log> showLog() {
		PageInfo<Log> pi = new PageInfo<Log>(mapper.selByPageStatic());
		return pi;
	}
	@Override
	public PageInfo<Log> showLog(int pageNum, int pageSize) {
		PageInfo<Log> pi = new PageInfo<Log>(mapper.selByPage(pageNum, pageSize));
		return pi;
	}
}

5.控制器servlet

ShowLogServlet.java

package com.zy.servlet;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;

import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.github.pagehelper.Page;
import com.github.pagehelper.PageHelper;
import com.github.pagehelper.PageInfo;
import com.zy.pojo.Log;
import com.zy.service.LogService;
import com.zy.service.impl.LogServiceImpl;

@WebServlet("/showLog")
public class ShowLogServlet extends HttpServlet{
	private LogService logService;
	@Override
	public void init() throws ServletException {
		WebApplicationContext wac = WebApplicationContextUtils.getWebApplicationContext(getServletContext());
		logService = wac.getBean("logServiceImpl",LogServiceImpl.class);
	}
	@Override
	protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
		req.setCharacterEncoding("utf-8");
		String pageNumStr = req.getParameter("pageNum");
		String pageSizeStr = req.getParameter("pageSize");
		String sortType = req.getParameter("sortType");
		int pageNum = 1;
		if (pageNumStr != null && !pageNumStr.equals("")) {
			pageNum = Integer.parseInt(pageNumStr.trim());
		}
		int pageSize = 10;
		if (pageSizeStr != null && !pageSizeStr.equals("")) {
			pageSize = Integer.parseInt(pageSizeStr.trim());
		}
		PageInfo<Log> pi ;
		if(sortType!=null && !sortType.trim().equals("") && //排序参数合法
				(sortType.trim().equals("asc") ||sortType.trim().equals("desc")) ) {
			PageHelper.startPage(pageNum,pageSize,"id "+sortType.trim());
			pi = logService.showLog();
		}else {
//			PageHelper.startPage(pageNum,pageSize);
//			pi = logService.showLog();
			//如果没有排序参数的话，就使用传参的方式
			pi = logService.showLog(pageNum, pageSize);
		}
		//获取到排序方式或者判断prePage与nextPage的大小就知道是按什么排序了
		//String orderBy = ((Page)pi.getList()).getOrderBy();
		//使用Ajax    设置响应内容
		resp.setContentType("application/json;charset=utf-8");
		PrintWriter out = resp.getWriter();
		//对象转json
		ObjectMapper mapper = new ObjectMapper();
		out.println(mapper.writeValueAsString(pi));
		out.flush();
		out.close();
	}
}

2. ssm+pagehelper+ajax分页显示日志信息

1. 数据准备、导入jar、web.xml、spring配置文件(applicationContext.xml)

数据准备：登录注册项目的操作日志表log

CREATE TABLE `log` (

 `time` datetime DEFAULT NULL COMMENT '操作时间',
 PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=150 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci;

导入jar包:
