SpringBoot全局路径设置

第一步，创建一个拦截器，实现前置处理方法

public class BasePathInterceptor extends HandlerInterceptorAdapter {

	@Override
	public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
		String scheme = request.getScheme();
		String serverName = request.getServerName();
		int port = request.getServerPort();
		String path = request.getContextPath();
		String homeUrl = scheme + "://" + serverName + ":" + port + path;
		request.setAttribute("ctx", homeUrl);
		return true;
	}
}

第二步，注册拦截器

@Configuration
public class WebConfiguration extends WebMvcConfigurerAdapter {
	@Override
	public void addInterceptors(InterceptorRegistry registry) {
		// 多个拦截器组成一个拦截器链
		registry.addInterceptor(new BasePathInterceptor()).addPathPatterns("/**");
		super.addInterceptors(registry);
	}
}

怎么用？

如果想引用上图目录下的jquery.min.js，看代码。

<script src="${ctx}/js/jquery.min.js"></script>
