spring boot 整合 freemark（簡單結構）
阿新 • • 發佈：2018-12-08
一、建立Mean 專案 這個就不多說了
二、我的spring boot demo 結構 如下：
三、主要的配置檔案（application.properties ；pom.xml ； log4j2.xml）
（1、）application.properties 檔案

</html>request.getContextPath() 的效果
需要重新定義 攔截器類和註冊類：
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;
/**
* 攔截器類
* @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 {
}
}註冊類：
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
/**
* 註冊類
* @author Michael
*
*/
@Configuration
public class CommonInterceptorConfig extends WebMvcConfigurerAdapter {
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new CommonInterceptor()).addPathPatterns("/**");
}
}
