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

（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);
}
@Override
protected 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 = "/")
@ResponseBody
public class StudentController {
@Autowired
private StudentBasisService studentService;
@RequestMapping(value = "Student/index.html", method = RequestMethod.GET)
public ModelAndView getStudentIndex(HttpServletRequest request) throws Exception {
ModelAndView mv = new ModelAndView("/student/index");
List list = new ArrayList();
Map whereMap = new HashMap();
list = studentService.getList(whereMap);
System.out.println("获取列表成功!");
mv.addObject("studentlist", list);
return mv;
}
}
<#assign boot = basePath >
学生列表
学生学号
学生姓名
手机号码
电子邮件
性别
操作
<#if (studentlist?? && studentlist?size>0)>
<#list studentlist as data>
${data.studentcode}
${data.studentname}
${data.mobile}
${data.email}
修改
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 {
@Override
public 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;
}
@Override
public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o,
ModelAndView modelAndView) throws Exception {
}
@Override
public 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
*
*/
@Configuration
public class CommonInterceptorConfig extends WebMvcConfigurerAdapter {
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new CommonInterceptor()).addPathPatterns("/**");
}
}
