9 . log4j日志

conf/log4j.properties

### set log levels ###
#log4j.rootLogger = debug , stdout , D , E
log4j.rootLogger = debug , stdout , D

###  output to the console ###
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
#log4j.appender.stdout.layout.ConversionPattern = %d{ABSOLUTE} %5p %c{ 1 }:%L - %m%n
log4j.appender.stdout.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [%c]-[%p] %m%n

### Output to the log file ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = ${springmvc.root}/WEB-INF/logs/log.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = DEBUG 
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n

### Save exception information to separate file ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = ${springmvc.root}/WEB-INF/logs/error.log 
log4j.appender.D.Append = true
log4j.appender.D.Threshold = ERROR 
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n
10 . 编写jsp和controller代码

WEB-INF/jsp/index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<h1>ssm搭建完成!!!</h1>
</body>
</html>

WEB-INF/jsp/allusers.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
    <h1>ssm搭建完成!!!</h1>
    id-------------用户昵称
    <hr>
    <c:forEach items="${users}" var="user">
    ${user.id }-------------${user.nickname }
        <hr>
    </c:forEach>
</body>
</html>

cn.SpringDemo.controller/UserComtroller.java

package cn.SpringDemo.controller;

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.RequestMapping;

import cn.SpringDemo.model.User;
import cn.SpringDemo.model.result.ResultDO;
import cn.SpringDemo.service.UserService;

/**
 * 用户Controller
 * @author yezi
 *
 */
@Controller
@RequestMapping("/")
public class UserController {

    @Autowired
    private UserService userService;

    /**
     * 测试
     * @return
     */
    @RequestMapping("index")
    public String index(){
        return "index";
    }

    @RequestMapping("showAllUsers")
    public String showAllUsers(Model model) {
        ResultDO<List<User>> resultDO = userService.getAllUsers();
        model.addAttribute("users", resultDO.getResult());
        return "allUsers";
    }
}
11.发布运行

将项目部署到tomcat8.5.16中

访问路径localhost:8080/SpringDemo/index.do

项目源码在这里,等本人稍微休息一会儿,正在抓紧时间上传完善中。。。

本人小小菜鸟,难免会有错误,希望大神们看到能够及时指出。৳৸ᵃᵑᵏ Ꮍ৹੫ᵎ
