swagger2自定义隐藏实体类属性

swagger2自定义隐藏实体类属性

作者: 吟风者 | 来源:发表于2019-07-23 15:08 被阅读0次

    假如接收参数的实体类中关联了其他对象，那么swagger2的页面中参数应该会多出来这些，dept.id，dept.deptName，或者集合属性，roles[0].id，roles[0].roleName等等。
    ​​​这些属性有可能是不需要用来接收参数的，出现在文档中会给前端开发人员带来困惑

    image

    笔者在swagger2提供的配置中没有找到隐藏此类参数的设置

    但是通过阅读源码找到了展开参数的类springfox.documentation.spring.web.readers.parameter.ModelAttributeParameterExpander，笔者通过继承这个类，并添加@Primary注解覆盖了源码中的逻辑，修改了getBeanPropertyNames方法，其他不变

    swagger2版本2.8.0 解决方案

            parameterType = "formData";
        }

        return parameterType;
    }
}

    用到了自定义的IgnoreSwaggerParamer注解

    
package com.example.annotation;
 
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
 
// swagger忽略的参数
@Target({ElementType.FIELD})
@Retention(RetentionPolicy.RUNTIME)
public @interface IgnoreSwaggerParameter {
}

    使用方式，在不需要递归展开的属性上加上IgnoreSwaggerParameter注解

    
package com.example.model.po;
 
import com.example.annotation.IgnoreSwaggerParameter;
import com.example.model.BaseModel;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
 
import java.sql.Date;
import java.sql.Timestamp;
import java.util.List;
 
@Data
@ApiModel(value = "用户")
public class User extends BaseModel {
 
    private static final long serialVersionUID = 1L;
    @ApiModelProperty(value = "用户id")
    private Integer id;
    @ApiModelProperty(value = "用户名")
    private String username;
    @ApiModelProperty(value = "密码")
    private String password;
    @ApiModelProperty(value = "邮箱")
    private String email;
    @ApiModelProperty(value = "昵称")
    private String nickname;
    @ApiModelProperty(value = "生日")
    private Date birth;
    @ApiModelProperty(value="登录时间")
    private Timestamp logintime;
    @ApiModelProperty(value = "部门id")
    private Integer deptId;
 
    @ApiModelProperty(value = "部门信息")
    @IgnoreSwaggerParameter // 在不需要递归展开的属性上加上IgnoreSwaggerParameter注解
    private Dept dept;
}

    这样就可以自定义隐藏swagger2页面中的参数了。

    如果有用的不对的地方，欢迎各位大佬批评指正。

    如有疑问请参考源码：swagger2,文档和示例略有不同，有什么疑问请留言。
