Springboot读取templates文件html代码实例

Springboot读取templates文件html代码实例

SpringBoot里面没有我们之前常规web开发的WebContent（WebApp），它只有src目录

在src/main/resources下面有两个文件夹，static和templates springboot默认 static中放静态页面，而templates中放动态页面

在不使用第三方jar包的情况下, Springboot不能直接访问templates下的静态页面, 需要加其他jar包依赖。

代码如下

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.stereotype.Controller;

import org.springframework.util.ClassUtils;

import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import java.io.*;

@Controller

public class PageController {

private static ClassLoader classLoader = ClassUtils.getDefaultClassLoader();

private static final Logger log = LoggerFactory.getLogger(PageController.classhttp://);

@RequestMapping("/")

public void root(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

request.getRequestDispatcher("/index.html").forward(request, response);

}

@RequestMapping("**.html")

public void page(HttpServletRequest requhttp://est, HttpServletResponse response) throws IOException {

InputStreamReader streamReader = null;

try {

String servletPath = request.getServletPath();

log.info(request.getMethod() + " " + servletPath);

String filePath = "templates" + servletPath;

InputStream inputStream = classLoader.getResourceAsStream(filePath);

if (inputStream == null) {

response.sendError(404);

return;

}

streamReader = new InputStreamReader(inputStream);

PrintWriter printWriter = response.getWriter();

response.setContentType("text/html");

int readChar;

while ((readChar = streamReader.read()) != -1) {

printWriter.write(readChar);

}

printWriter.flush();

} finally {

if (streamReader != null) streamReader.close();

}

}
