spring boot 整合 freemark（简单结构）

一、创建Mean 项目  这个就不多说了

二、我的spring boot demo 结构 如下：

三、主要的配置文件（application.properties ；pom.xml ； log4j2.xml）

（1、）application.properties 文件

（3、）log4j2.xml

（4、程序主入口）

package com.myspringboot;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.boot.builder.SpringApplicationBuilder;import org.springframework.boot.web.support.SpringBootServletInitializer;/** * @ClassName: Application * @Description:项目启动入口 *///@EnableCaching //缓存//@EnableScheduling //定时任务//@EnableAsync //异步任务@SpringBootApplication // 项目启动//@ComponentScan("com.myspringboot")public class Application extends SpringBootServletInitializer {public static void main(String[] args) throws Exception {SpringApplication.run(Application.class, args);}@Overrideprotected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {return builder.sources(this.getClass());}}

（5、）控制器

import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import javax.servlet.http.HttpServletRequest;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.ResponseBody;import org.springframework.web.servlet.ModelAndView;import com.myspringboot.model.StudentBasis;import com.myspringboot.service.StudentBasisService;@Controller@RequestMapping(value = "/")@ResponseBodypublic class StudentController {@Autowiredprivate StudentBasisService studentService;@RequestMapping(value = "Student/index.html", method = RequestMethod.GET)public ModelAndView getStudentIndex(HttpServletRequest request) throws Exception {ModelAndView mv = new ModelAndView("/student/index");List<StudentBasis> list = new ArrayList<StudentBasis>();Map<String, Object> whereMap = new HashMap<String, Object>();list = studentService.getList(whereMap);System.out.println("获取列表成功!");mv.addObject("studentlist", list);return mv;}}

（6、）前台页面

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"><#assign boot = basePath ><html><head>    <title>学生列表</title>    <base href="${boot}/" />    <meta http-equiv="content-type" content="text/html;charset=utf-8" />    <link type="text/css" rel="stylesheet" href="${boot}/public/css/base.css" />    <link type="text/css" rel="stylesheet" href="${boot}/public/css/master.css" />    <script type="text/javascript" language="javascript" src="${boot}/public/js/jquery-2.2.1.min.js"></script></head><body>   <table class="week_pro"><tr><th>学生学号</th><th>学生姓名</th><th>手机号码</th><th>电子邮件</th><th style="width: 80px;">性别</th><th style="width: 120px;">操作</th></tr><#if (studentlist?? && studentlist?size>0)><#list studentlist as data><tr><td>${data.studentcode}</td><td>${data.studentname}</td><td>${data.mobile}</td><td>${data.email}</td><td></td><td><a class="btn_link" id='${data.id}'>修改</a></td></tr></#list></#if></table></body></html>

（7、）如果在前台页面 要想与jsp 那样获取 

request.getContextPath() 的效果

需要重新定义 拦截器类和注册类：

import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.web.servlet.HandlerInterceptor;import org.springframework.web.servlet.ModelAndView;/** *  拦截器类 * @author Michael * */public class CommonInterceptor implements HandlerInterceptor {@Overridepublic boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o)throws Exception {String path = httpServletRequest.getContextPath();String scheme = httpServletRequest.getScheme();String serverName = httpServletRequest.getServerName();int port = httpServletRequest.getServerPort();String basePath = scheme + "://" + serverName + ":" + port + path;httpServletRequest.setAttribute("basePath", basePath);return true;}@Overridepublic void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o,ModelAndView modelAndView) throws Exception {}@Overridepublic void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse,Object o, Exception e) throws Exception {}}

注册类：

import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.config.annotation.InterceptorRegistry;import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;/** * 注册类 * @author Michael * */@Configurationpublic class CommonInterceptorConfig extends WebMvcConfigurerAdapter {    @Override    public void addInterceptors(InterceptorRegistry registry) {        registry.addInterceptor(new CommonInterceptor()).addPathPatterns("/**");    }}
