我使用Spring Cloud和Zuul代理作为我的RESTful服务的网关。
网关应用程序(在端口8080上运行的Spring Boot Web应用程序)相关代码: -
主要课程: -
@SpringBootApplication
@EnableZuulProxy
public class WebfrontApplication extends WebMvcConfigurerAdapter {
/**
* @param args
*/
public static void main(String[] args) {
SpringApplication.run(WebfrontApplication.class, args);
}
}
Zuul Mappings: -
zuul:
routes:
customer:
path: /customer/**
url: http://localhost:9000/
在启动上述UI网关应用程序期间,我可以在我的日志中看到已注册代理的映射: -
o.s.c.n.zuul.web.ZuulHandlerMapping : Mapped URL path [/customer/**] onto handler of type [class org.springframework.cloud.netflix.zuul.web.ZuulController]
REST服务(在端口9000上运行的Spring Boot Web应用程序)相关代码: -
@RestController
@RequestMapping(value = "/customer")
public class CustomerController {
@Autowired
private CustomerService customerService;
/**
* Get List of All customers.
*
* @return
*/
@RequestMapping(value = "/list", method = RequestMethod.GET)
public List<Customer> list(Principal principal) {
return customerService.list();
}
}
使用rest客户端(在我的情况下是POSTMAN)我能够成功地从上面的端点获得响应(在处理身份验证令牌之后)。
我在UI应用程序中使用AngularJS从REST端点获取数据。
相关代码: -
angular.module('customerModule').factory('customerService',function($http) {
return {
customerList : function(){
// PROBLEM !!!!!
// THIS CALL GIVES A 404 ERROR
return $http.get('/customer/list');
}
};
});
以上电话回复404错误: - 这是我的Chrome调试器显示的内容: -

这里有什么问题?映射是不正确的还是我错过了其他的东西?
解决
根据接受的答案,更改Zuul映射时更改为: -
zuul:
routes:
resource:
path: /customer/**
url: http://localhost:9000/
stripPrefix: false
答案 0 :(得分:9)
资源服务器上没有“/ list”的映射(所以它是404)。您需要在路由声明中设置stripPrefix = false,或者将后端的请求映射更改为“/".
答案 1 :(得分:-1)
如果您不想设置stripPrefix
属性,也可以尝试以下配置:
zuul:
routes:
customer:
path: /customer/**
url: http://localhost:9000/customer
