根据弹簧活动配置文件修改映射路线

Question

我希望在开发和生产环境中使用不同的控制器映射路径。我曾与@ConditionalOnExpression试过，但似乎它消除了@RequestMapping注释，以及如果条件为假：

@RestController 
@RequestMapping(value = "/dev") 
@ConditionalOnExpression("#{environment.getActiveProfiles()[0] == 'DEV'}") 
public class CheckoutController { 

我想前缀“/ dev的”添加到所有映射路径如果当前情景是DEV。

Answer 1

我建议创建2个不同的控制器。每个人对自己的个人资料

@RestController 
@RequestMapping(value = "/dev") 
@ConditionalOnExpression("#{environment.getActiveProfiles()[0] == 'DEV'}") 
public class DevCheckoutController { 

和

@RestController 
@RequestMapping(value = "/prod") 
@ConditionalOnExpression("#{environment.getActiveProfiles()[0] == 'PROD'}") 
public class ProdCheckoutController { 

另一个（更复杂的）方法是重写RequestMappingHandlerMapping。你需要这个方法。

protected RequestMappingInfo createRequestMappingInfo(
     RequestMapping requestMapping, RequestCondition<?> customCondition) { 

    return RequestMappingInfo 
      .paths(resolveEmbeddedValuesInPatterns(requestMapping.path())) 
      .methods(requestMapping.method()) 
      .params(requestMapping.params()) 
      .headers(requestMapping.headers()) 
      .consumes(requestMapping.consumes()) 
      .produces(requestMapping.produces()) 
      .mappingName(requestMapping.name()) 
      .customCondition(customCondition) 
      .options(this.config) 
      .build(); 
} 

在.paths(resolveEmbeddedValuesInPatterns(requestMapping.path()))只需添加一个取决于配置文件的值。所以，你添加的环境

@Autowired 
Environment env; 

和方法应该是这样的

String prefix = "DEV".equals(env.getActiveProfiles()[0]) ? "DEV" : "" 
return RequestMappingInfo 
      .paths(prefix + resolveEmbeddedValuesInPatterns(requestMapping.path())) 

还有一个方法是把一个表达式添加到您的映射

@RequestMapping(value = "/${my.profile.property:}prod") 

和DEV轮廓只是定义财产

my.profile.property=DEV
