如何仅为rest控制器更改基url？

Question

我使用的是spring boot V1.3.2

我尝试创建自定义注释，它通过添加RequestMapping来扩展RestController。这里有一个例子，但它不起作用。

@Target(ElementType.TYPE) 
@Retention(RetentionPolicy.RUNTIME) 
@RestController 
@RequestMapping(value = "/rest", path = "/rest") 
public @interface MyRestController { }

创建一个声明基本URL的自定义注释，并使用它来代替@RestController。

CustomRestControllerAnnotation.java

package com.example.stackoverflow.config;

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@RestController
@RequestMapping("/rest")
public @interface CustomRestControllerAnnotation {}

firstRestController.java

package com.example.stackoverflow.controller;

import org.springframework.web.bind.annotation.RequestMapping;

import com.example.stackoverflow.config.CustomRestControllerAnnotation;

@CustomRestControllerAnnotation
public class FirstRestController {

    @RequestMapping("/first")
    public String firstMethod(){
        return "First Controller";
    }
}

secondrestController.java

package com.example.stackoverflow.controller;

import org.springframework.web.bind.annotation.RequestMapping;

import com.example.stackoverflow.config.CustomRestControllerAnnotation;

@CustomRestControllerAnnotation
public class SecondRestController {

    @RequestMapping("/second")
    public String secondMethod(){
        return "Second Controller";
    }
}

通过创建一个用作所有实际控制器模板的基控制器，您可以从一个位置有效地管理根URL。

BaseRestController.java

package com.example.stackoverflow.controller;

import org.springframework.web.bind.annotation.RequestMapping;

@RequestMapping("/rest")
public class BaseRestController {}

package com.example.stackoverflow.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class FirstRestController extends BaseRestController{

    @RequestMapping("/first")
    public String firstMethod(){
        return "First Controller";
    }
}

package com.example.stackoverflow.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class SecondRestController extends BaseRestController{

    @RequestMapping("/second")
    public String secondMethod(){
        return "Second Controller";
    }
}

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-rest</artifactId>
</dependency>

通过声明这种依赖关系，您的所有存储库都会自动启用REST。

可以使用属性文件控制基URL。

应用程序.属性

spring.data.rest.basePath=/rest
