java - 根据 spring Activity 配置文件修改映射路径

Question

我希望 Controller 的开发和生产环境有不同的映射路线。我已经使用 @ConditionalOnExpression 尝试过此操作，但如果条件为 false，它似乎也会删除 @RequestMapping 注释:

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

如果 Activity 配置文件是 DEV，我想向所有映射路由添加前缀“/dev”。

Answer 1

我建议创建 2 个不同的 Controller 。每一项都有自己的个人资料

@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 {

另一种(更复杂)的方法是重写RequestMappingHandlerMapping。您需要该方法。

    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())) 中，只需根据配置文件添加一个值。所以你添加环境

@Autowired
Environment env;

方法应该是这样的

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

另一种方法是仅向映射添加表达式

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

对于 DEV 配置文件，只需定义属性

my.profile.property=DEV
