先检查Maven中包是否导入, 以下以idea为列. 看是否有 swagger-ui 这个包

 

 

以下为代码配置:

 

package net.ainio.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class SwaggerConfig {
    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                // 自行修改为自己的包路径
                .apis(RequestHandlerSelectors.basePackage("net.ainio.controller"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("api文档")
                .description("restfun 风格接口")
                //服务条款网址
                //.termsOfServiceUrl("http://blog.csdn.net/forezp")
                .version("1.0")
                //.contact(new Contact("帅呆了", "url", "email"))
                .build();
    }
}

 

测试controller

注意下这两个的区别哦, 不然前台会返回 404 错误

@RestController

@Controller

package net.ainio.controller;

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiOperation;
import org.apache.catalina.User;
import org.springframework.web.bind.annotation.*;

@Api(value="/test", tags="测试接口模块")
@RestController
@RequestMapping("/test")
public class TestSwaggerController {
    @ApiOperation(value="展示首页信息", notes = "展示首页信息")
    @GetMapping("/show")
    public Object showInfo(){
        return "hello world";
    }

    @ApiOperation(value="添加用户信息", notes = "添加用户信息")
    @ApiImplicitParam(name="user", value="User", required = true, dataType = "User")
    @PostMapping("/addUser")
    public Object addUser(@RequestBody User user){
        return "success";
    }
}

 

启动后访问

http://localhost:8080/swagger-ui.html
