如何在Spring Boot中为所有控制器指定前缀？ [英] How to specify prefix for all controllers in Spring Boot?

问题描述

我有控制器映射到 / user 和 / order ：

@RestController
@RequestMapping("/users")
public class UserController {
    ...
}

@RestController
@RequestMapping("/orders")
public class OrderController {
    ...
}

我想通过URL访问这些 http：// localhost：8080 / api / users 和 http：// localhost：8080 / api / orders 。

I want to access these by URL at http://localhost:8080/api/users and http://localhost:8080/api/orders, respectively.

我如何实现这一目标春季靴子？

推荐答案

您可以提供弹簧启动应用程序的根上下文路径到 / api / *的映射在您的自定义配置中。

You can provide a mapping to root context path of your spring boot application to /api/* in your custom configuration.

import org.springframework.boot.autoconfigure.web.DispatcherServletAutoConfiguration;
import org.springframework.boot.context.embedded.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.DispatcherServlet;

@Configuration
public class DispatcherServletCustomConfiguration {

    @Bean
    public DispatcherServlet dispatcherServlet() {
        return new DispatcherServlet();
    }

    @Bean
    public ServletRegistrationBean dispatcherServletRegistration() {
        ServletRegistrationBean registration = new ServletRegistrationBean(
                dispatcherServlet(), "/api/");
        registration.setName(DispatcherServletAutoConfiguration.DEFAULT_DISPATCHER_SERVLET_REGISTRATION_BEAN_NAME);
        return registration;
    }
}

或将此项添加到您的 application.properties in src\main\resources folder

or add this to your application.properties in src\main\resources folder

server.contextPath=/api/*
