1、源码链接：

springboot-swagger2（实体类的模型展示，controller接口的展示）： https://files.cnblogs.com/files/blogs/721495/springboot-swagger2.zip?t=1648827391

2、接口可视化展示

实际开发过程中，你不会还在controller层去一个个找你想要的接口嘛，去了公司我也才学会，为了更加的方便，可视化界面去展示项目的接口。我也是个菜鸡。

3、源码部分（可直接下载源码）

3.1 导入依赖

    io.springfox
    springfox-swagger2
    2.9.2


    io.springfox
    springfox-swagger-ui
    2.9.2

 3.2 定义实体类

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Getter;
import lombok.Setter;
import lombok.ToString;

@Getter
@Setter
@ToString
@ApiModel(value = "用户实体类", description = "用户信息描述类")
public class User {    

@ApiModelProperty(value = "用户id")    
private Integer id;    

@ApiModelProperty(value = "用户名")    
private String username;    

@ApiModelProperty(value = "用户密码")    
private String password;
}

3.3 编写controller层

import com.yzu.swagger2.entity.User;
import io.swagger.annotations.*;
import org.springframework.web.bind.annotation.*;
import springfox.documentation.annotations.ApiIgnore;

@RestController
@Api(tags = "用户数据接口")
public class UserController {

    @ApiOperation(value ="查询用户", notes = "根据 id 查询用户")
    @ApiImplicitParam(paramType = "path", name = "id", value = "用户 id", required = true)
    @GetMapping("/user/{id}")
    public String getUserById(@PathVariable Integer id){
        return "查找的用户id是：" + id;
    }

    @ApiOperation(value = "新增用户", notes = "根据传入的用户名和密码添加一个新用户")
    @ApiImplicitParams({
            @ApiImplicitParam(paramType = "query", name = "username",
                    value = "用户名", required = true, defaultValue = "test"),
            @ApiImplicitParam(paramType = "query", name = "password",
                    value = "密码", required = true, defaultValue = "123")
    })
    @PostMapping("/user")
    public String addUser(@RequestParam String username, @RequestParam String password) {
        return "新增用户：" + username + " " + password;
    }

    @ApiOperation(value = "删除用户", notes = "根据 id 删除用户")
    @ApiResponses({
            @ApiResponse(code = 200, message = "删除成功！"),
            @ApiResponse(code = 500, message = "删除失败！")
    })
    @DeleteMapping("/user/{id}")
    public Integer deleteUserById(@PathVariable Integer id) {
        return id;
    }

    @ApiOperation(value = "修改用户", notes = "传入用户信息进行更新修改")
    @PutMapping("/user")
    public String updateUser(@RequestBody User user){
        return user.toString();
    }

    @ApiIgnore
    @GetMapping("/user/test")
    public String test() {
        return "这是一个测试接口，不需要在api文档中显示。";
    }
}

 3.4 编写配置类

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.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
//@EnableSwaggerBootstrapUI
public class SwaggerConfig {

    @Bean
    Docket docket() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.yzu.swagger2.controller"))
                .paths(PathSelectors.any())
                .build();
    }

　　//这边主要是网页界面中展示内容
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("API的测试文档")
                .description("DEMO项目的接口测试文档")
                .version("1.0")
                .build();
    }

}

 3.5 网页展示
