在軟件開發(fā)中,編寫接口文檔是一項必要但繁瑣的任務(wù),為了簡化這一過程,可以通過使用Swagger2和Swagger-UI來自動生成接口文檔,這篇文章主要介紹了java自動生成接口文檔的相關(guān)資料,需要的朋友可以參考下

maven依賴

要使用javamail的jar包首先需要導(dǎo)入依賴

<!--Swagger-UI API文檔生產(chǎn)工具-->
<dependency>
	<groupId>io.springfox</groupId>
	<artifactId>springfox-swagger2</artifactId>
	<version>2.7.0</version>
</dependency>
<dependency>
	<groupId>io.springfox</groupId>
	<artifactId>springfox-swagger-ui</artifactId>
	<version>2.7.0</version>
</dependency>
<!--整合Knife4j-->
<dependency>
	<groupId>com.github.xiaoymin</groupId>
	<artifactId>knife4j-spring-boot-starter</artifactId>
	<version>2.0.4</version>
</dependency>

這里我們整合了swagger2和swagger-ui

swagger-ui是在swagger2的基礎(chǔ)上對頁面的展示效果進(jìn)行一定的優(yōu)化

工具類

Swagger2API文檔的配置

import com.github.xiaoymin.knife4j.spring.annotations.EnableKnife4j;
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;

/**
 * Swagger2API文檔的配置
 */
@Configuration
@EnableSwagger2
@EnableKnife4j
public class Swagger2Config {
    @Bean
    public Docket createRestApi(){
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                //為當(dāng)前包下controller生成API文檔
                .apis(RequestHandlerSelectors.basePackage("huafu.controller"))
                //為有@Api注解的Controller生成API文檔
//                .apis(RequestHandlerSelectors.withClassAnnotation(Api.class))
                //為有@ApiOperation注解的方法生成API文檔
//                .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("華富項目演示")
                .description("huafu")
                .version("1.0")
                .build();
    }
}

這個是接口返回的工具類

import io.swagger.annotations.ApiModelProperty;

/**
 * 通用返回對象
 * Created by macro on 2019/4/19.
 */
public class CommonResult<T> {

    @ApiModelProperty(value = "返回代碼")
    private String code;
    @ApiModelProperty(value = "返回信息")
    private String message;
    @ApiModelProperty(value = "返回數(shù)據(jù)")
    private T data;

    protected CommonResult() {
    }

    protected CommonResult(String code, String message, T data) {
        this.code = code;
        this.message = message;
        this.data = data;
    }

    /**
     * 成功返回結(jié)果
     *
     * @param data 獲取的數(shù)據(jù)
     */
    public static <T> CommonResult<T> success(T data) {
        return new CommonResult<T>(ResultCode.SUCCESS.getCode(), ResultCode.SUCCESS.getMessage(), data);
    }

    /**
     * 成功返回結(jié)果
     *
     * @param data 獲取的數(shù)據(jù)
     * @param  message 提示信息
     *
     */
    public static <T> CommonResult<T> success(T data, String message) {
        return new CommonResult<T>(ResultCode.SUCCESS.getCode(), message, data);
    }

    /**
     * 失敗返回結(jié)果
     * @param errorCode 錯誤碼
     */
    public static <T> CommonResult<T> failed(IErrorCode errorCode) {
        return new CommonResult<T>(errorCode.getCode(), errorCode.getMessage(), null);
    }

    /**
     * 失敗返回結(jié)果
     * @param message 提示信息
     */
    public static <T> CommonResult<T> failed(String message) {
        return new CommonResult<T>(ResultCode.FAILED.getCode(), message, null);
    }

    /**
     * 失敗返回結(jié)果
     */
    public static <T> CommonResult<T> failed() {
        return failed(ResultCode.FAILED);
    }

    /**
     * 參數(shù)驗證失敗返回結(jié)果
     */
    public static <T> CommonResult<T> validateFailed() {
        return failed(ResultCode.VALIDATE_FAILED);
    }

    /**
     * 參數(shù)驗證失敗返回結(jié)果
     * @param message 提示信息
     */
    public static <T> CommonResult<T> validateFailed(String message) {
        return new CommonResult<T>(ResultCode.VALIDATE_FAILED.getCode(), message, null);
    }

    /**
     * 未登錄返回結(jié)果
     */
    public static <T> CommonResult<T> unauthorized(T data) {
        return new CommonResult<T>(ResultCode.UNAUTHORIZED.getCode(), ResultCode.UNAUTHORIZED.getMessage(), data);
    }

    /**
     * 未授權(quán)返回結(jié)果
     */
    public static <T> CommonResult<T> forbidden(T data) {
        return new CommonResult<T>(ResultCode.FORBIDDEN.getCode(), ResultCode.FORBIDDEN.getMessage(), data);
    }

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public T getData() {
        return data;
    }

    public void setData(T data) {
        this.data = data;
    }
}

這里可以根據(jù)自己的實際需求自定義返回內(nèi)容

/**
 * 枚舉了一些常用API操作碼
 * Created by macro on 2019/4/19.
 */
public enum ResultCode implements IErrorCode {
    SUCCESS("0", "成功"),
    FAILED("500", "失?。?),
    VALIDATE_FAILED("404", "參數(shù)檢驗失敗"),
    UNAUTHORIZED("401", "暫未登錄或token已經(jīng)過期"),
    FORBIDDEN("403", "沒有相關(guān)權(quán)限");
    private String code;
    private String message;

    private ResultCode(String code, String message) {
        this.code = code;
        this.message = message;
    }

    public String getCode() {
        return code;
    }

    public String getMessage() {
        return message;
    }
}

/**
 * 封裝API的錯誤碼
 * Created by macro on 2019/4/19.
 */
public interface IErrorCode {
    String getCode();

    String getMessage();
}

實體類每個字段上面需要添加@ApiModelProperty對字段進(jìn)行結(jié)束說明

import io.swagger.annotations.ApiModelProperty;
import java.io.Serializable;

public class User implements Serializable {
    @ApiModelProperty(value = "主鍵")
    private Integer id;

    @ApiModelProperty(value = "用戶名 郵箱地址")
    private String userName;

    @ApiModelProperty(value = "登陸密碼 md5加密")
    private String password;

    @ApiModelProperty(value = "郵箱地址")
    private String email;

    @ApiModelProperty(value = "matrixId")
    private Integer matrixId;

    @ApiModelProperty(value = "是否從matrix跳轉(zhuǎn) 1:是 0:否")
    private Integer isMatrix;

    @ApiModelProperty(value = "用戶狀態(tài)  1:正常  0:注銷")
    private Integer status;

    private static final long serialVersionUID = 1L;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName == null ? null : userName.trim();
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password == null ? null : password.trim();
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email == null ? null : email.trim();
    }

    public Integer getMatrixId() {
        return matrixId;
    }

    public void setMatrixId(Integer matrixId) {
        this.matrixId = matrixId;
    }

    public Integer getIsMatrix() {
        return isMatrix;
    }

    public void setIsMatrix(Integer isMatrix) {
        this.isMatrix = isMatrix;
    }

    public Integer getStatus() {
        return status;
    }

    public void setStatus(Integer status) {
        this.status = status;
    }

    @Override
    public String toString() {
        StringBuilder sb = new StringBuilder();
        sb.append(getClass().getSimpleName());
        sb.append(" [");
        sb.append("Hash = ").append(hashCode());
        sb.append(", id=").append(id);
        sb.append(", userName=").append(userName);
        sb.append(", password=").append(password);
        sb.append(", email=").append(email);
        sb.append(", matrixId=").append(matrixId);
        sb.append(", isMatrix=").append(isMatrix);
        sb.append(", status=").append(status);
        sb.append(", serialVersionUID=").append(serialVersionUID);
        sb.append("]");
        return sb.toString();
    }
}

接下來的controller的配置

//接口文檔地址：http://localhost:8090/swagger-ui.html   http://127.0.0.1:8090/doc.html
//自動生成 執(zhí)行Generator中的main方法
@Api(tags = "TestController", description = "商品品牌管理")
@Controller
@RequestMapping("/test")
public class TestController {

    private static Logger logger = LoggerFactory.getLogger(TestController.class);

    @ApiImplicitParams({
            @ApiImplicitParam(name = "id", value = "用戶ID", required=false, dataType = "Integer", paramType = "query")
    })
    @ApiOperation("測試普通請求方式")
    @RequestMapping(value = "listAll", method = RequestMethod.GET)
    @ResponseBody
    public CommonResult<User> get(@RequestParam(value = "id", required = false) Integer id) {
        User user = new User();
        user.setId(1);
        user.setEmail("xxxxxxx@qq.com");
        user.setMatrixId(2);
        user.setPassword("password");
        user.setStatus(1);
        user.setUserName("xxxx");
        return CommonResult.success(user);
    }

    @ApiImplicitParams({
            @ApiImplicitParam(name = "user", value = "用戶ID", required=false, dataType = "User", paramType = "body")
    })
    @ApiOperation("測試json請求方式")
    @RequestMapping(value = "madan", method = RequestMethod.POST)
    @ResponseBody
    public CommonResult<User> post(@RequestBody User user, HttpServletRequest request, HttpServletResponse response) {

        logger.info(" 獲取到的參數(shù) param:{}", user);
        return CommonResult.success(user);
    }

}

以上代碼即完成了所有自動接口文檔的開發(fā) 接下來我們看看效果
