controller 增加指定前缀
1、增加配置
server.servlet.context-path: /api这种是最常见的，加上这个配置后，所有的url，必须带上/api的前缀，才能访问到该url
2、过滤拦截
这种是加上/api也可以访问，不加/api也可以访问，适合项目重构修改的适合用
import org.apache.commons.lang.StringUtils;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.annotation.Order;
import javax.servlet.*;
import javax.servlet.annotation.WebFilter;
import javax.servlet.http.HttpServletRequest;
import java.io.IOException;
@Configuration
@Order(1)
@WebFilter(filterName = "urlFilter", urlPatterns = "/api/*")
public class UrlFilter implements Filter {
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
HttpServletRequest httpRequest = (HttpServletRequest) request;
String servletPath = httpRequest.getServletPath();
if (StringUtils.isNotBlank(servletPath) && servletPath.startsWith("/api")) {
String newPath = servletPath.substring(4);
request.getRequestDispatcher(newPath).forward(request, response);
} else {
chain.doFilter(request, response);
}
}
@Override
public void destroy() {
}
}
springboot服务端口、项目前缀的配置
在application.properties中配置
server.port: 8081
server.context-path: /demo以上为个人经验，希望能给大家一个参考，也希望大家多多支持编程网。
