如何在Spring Boot中为所有控制器指定前缀？

Question

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

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

我想通过URL分别访问http://localhost:8080/api/users和http://localhost:8080/api/orders。

如何在Spring Boot中实现这一点？

Answer 1

您可以在自定义配置中为/api/*提供到Spring Boot应用程序根上下文路径的映射。

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;
    }
}

或者将其添加到src\main\resources文件夹中的application.properties中

server.contextPath=/api/*

编辑

server.servlet.contextPath=/api/*
