SpringBoot controller添加URL统一前缀

给项目统一加前缀，这个基本都是知道，设置context-path。 如果是给模块加统一前缀，要怎么弄呢？

## 1，添加统一前缀 ##

yml里面设置：

server:
        port: 8081
        servlet:
            context-path: /api/v1

## 2，给模块添加统一前缀 ##

使用自定义注解的方式：

### ApiPrefix ###

import io.swagger.annotations.ApiModel;
    import io.swagger.annotations.ApiModelProperty;
    import lombok.Data;
    //import org.springframework.beans.factory.annotation.Value;
    import org.springframework.boot.context.properties.ConfigurationProperties;
    import org.springframework.stereotype.Component;
    
    @Data
    @Component
    @ConfigurationProperties(prefix = "url.api.prefix")
    @ApiModel(value = "url的Api前缀")
    public class ApiPrefix {
        @ApiModelProperty("流程模块的前缀")
        // @Value("${url.api.prefix.flow}")
        private String flow;
    
        @ApiModelProperty("通用模块的前缀")
        // @Value("${url.api.prefix.common}")
        private String common;
    
        @ApiModelProperty("用户模块的前缀")
        // @Value("${url.api.prefix.user}")
        private String user;
    
    }

这边使用 @ConfigurationProperties(prefix = "url.api.prefix") 的方式，比 @Value的方式更为简便

### ApiPrefixFlowRestController ###

import org.springframework.web.bind.annotation.RestController;
    
    import java.lang.annotation.*;
    
    @RestController
    @Documented
    @Target(ElementType.TYPE)
    @Retention(RetentionPolicy.RUNTIME)
    public @interface ApiPrefixFlowRestController {
    
    }

### ApiPrefixCommonRestController ###

### ApiPrefixUserRestController ###

### WebMvcConfig ###

@Configuration
    public class WebMvcConfig implements WebMvcConfigurer {
    
        @Resource
        private ApiPrefix apiPrefix;
    
        @Override
        public void configurePathMatch(PathMatchConfigurer configurer) {
            configurer.addPathPrefix(apiPrefix.getFlow(), c -> c.isAnnotationPresent(ApiPrefixFlowRestController.class));
            configurer.addPathPrefix(apiPrefix.getCommon(), c -> c.isAnnotationPresent(ApiPrefixCommonRestController.class));
            configurer.addPathPrefix(apiPrefix.getUser(), c -> c.isAnnotationPresent(ApiPrefixUserRestController.class));
        }
    
    }

#### yml配置： ####

server:
        port: 8081
        servlet:
            context-path: /api/v1
    
    url:
      api:
        prefix:
          flow: flow
          common: common
          user: user

### 测试： ###

#### TestApiPrefixFlowRestController ####

@ApiPrefixFlowRestController
    @RequestMapping("/prefix")
    public class TestApiPrefixFlowRestController {
    
        @GetMapping(value = "/getInfo")
        public String get() {
            return "flow prefix";
        }
    }

#### TestApiPrefixCommonRestController ####

@ApiPrefixCommonRestController
    @RequestMapping("/prefix")
    public class TestApiPrefixCommonRestController {
    
        @GetMapping(value = "/getInfo")
        public String get() {
            return "common prefix";
        }
    }

#### TestApiPrefixUserRestController ####

@ApiPrefixUserRestController
    @RequestMapping("/prefix")
    public class TestApiPrefixUserRestController {
    
        @GetMapping(value = "/getInfo")
        public String get() {
            return "user prefix";
        }
    
    }

#### 结果： ####

## 总结： ##

如果是使用模块加统一前缀，适合使用注解的方式。 对于需要加前缀的Controller加对应的注解，这样就比较方便。
