说明

swagger的使用本身是非常简单的，因为所有的一切swagger都帮你做好了，你所要做的就是专注写你的api信息
swagger自动生成html文档并且打包到jar包中
本文不仅用了swagger，JSR 303注释信息也支持使用

依赖

// springfox-bean-validators 用来支持 JSR 303

SwaggerConfig

package com.springlearn.learn.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
import springfox.bean.validators.configuration.BeanValidatorPluginsConfiguration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
import static springfox.documentation.builders.PathSelectors.regex;
@Configuration
@EnableSwagger2
@Import(BeanValidatorPluginsConfiguration.class)
public class SwaggerConfig extends WebMvcConfigurationSupport {
    private ApiInfo metaData() {
        return new ApiInfoBuilder()
                .title("Spring Boot REST API")
                .description("\"REST API 测试\"")
                .version("1.0.0")
                .license("无")
                .licenseUrl("https://www.baidu.com")
                .contact(new Contact("yejiawei", "https://www.cnblogs.com/ye-hcj/", "2640199637@qq.com"))
                .build();
    }
    @Bean
    public Docket productApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.springlearn.learn.controller"))
                .paths(regex("/.*"))
                .build()
                .apiInfo(metaData());
    }
    @Override
    protected void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("swagger-ui.html")
                .addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars/**")
                .addResourceLocations("classpath:/META-INF/resources/webjars/");
    }
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**").allowedOrigins("*").allowedMethods("GET", "POST", "PUT", "DELETE").allowedOrigins("*")
        .allowedHeaders("*");
    }
}

开启api界面

在你做好了上述的步骤以后，运行项目
直接访问 yourapiurl/v2/api-docs 查看json数据
直接访问 yourapiurl/swagger-ui.html 查看文档界面

JSR 303注释信息

@NotNull(message = "...")
@NotBlank(message = "...")
@Pattern(regexp = "[a-z-A-Z]*", message = "...")
@Past(message = "过去的日期...")
@Min(value = 1, message = "必须大于或等于1")
@Max(value = 10, message = "必须小于或等于10")
@Email(message = "Email Address")

Swagger核心注释

@ApiModel               返回json对象描述
@ApiModelProperty       返回json对象属性描述
@ApiResponses           设置状态码含义
@Api                    控制器描述
@ApiOperation           api描述
@ApiParam               api参数描述

User

package com.springlearn.learn.model;
import javax.validation.constraints.Max;
import javax.validation.constraints.Min;
import javax.validation.constraints.NotBlank;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Pattern;
import javax.validation.constraints.Size;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
@ApiModel(description = "用户基本信息")
public class User {
    // @NotBlank
    // @Size(min = 1, max = 10)
    @ApiModelProperty(notes = "用户姓名", example = "叶家伟", required = true, position = 0)
    String name;
    // @NotBlank
    @Pattern(regexp ="[m|f]")
    @ApiModelProperty(notes = "用户性别", example = "m", required = true, position = 1)
    Character sex;
    // @NotNull
    // @Min(0)
    // @Max(100)
    @ApiModelProperty(notes = "用户年龄", example = "19", position = 3)
    Integer age;
    public String getname() {
        return name;
    }
    public void setname(String name) {
        this.name = name;
    }
    public Character getsex() {
        return sex;
    }
    public void setsex(Character sex) {
        this.sex = sex;
    }
    public Integer getage() {
        return age;
    }
    public void setage(Integer age) {
        this.age = age;
    }
}

TestController

package com.springlearn.learn.controller;
import javax.servlet.http.HttpServletRequest;
import com.springlearn.learn.model.User;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;
import io.swagger.annotations.ApiResponse;
import io.swagger.annotations.ApiResponses;
@RestController
@Api(value="测试控制器", description="测试控制器描述")
@ApiResponses(value = {
    @ApiResponse(code = 200, message = "Successfully retrieved list"),
    @ApiResponse(code = 401, message = "You are not authorized to view the resource"),
    @ApiResponse(code = 403, message = "Accessing the resource you were trying to reach is forbidden"),
    @ApiResponse(code = 404, message = "The resource you were trying to reach is not found")
})
public class TestController {
    @ResponseBody
    @RequestMapping(value = "/test1/{id}", method = RequestMethod.GET, produces = "application/json")
    @ApiOperation(value = "测试api", response = User.class)
    public User Test1(HttpServletRequest request, @ApiParam("Id of the person to be obtained. Cannot be empty.") @PathVariable int id){
        User user = new User();
        user.setname("叶家伟");
        user.setage(18);
        user.setsex('m');
        return user;
    }
}
