Swagger异常：java.lang.NumberFormatException: For input string: ""

问题

项目整合Swagger，访问Swagger首页时后台抛出下面异常：

i.s.m.p.AbstractSerializableParameter : Illegal DefaultValue null for parameter type integer
java.lang.NumberFormatException: For input string: ""

原因好像是说swagger2本身引用的swagger-models-1.5.20.jar有bug
<br/>

解决

导入下面的maven坐标：

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.9.2</version>
    <exclusions>
        <exclusion>
            <groupId>io.swagger</groupId>
            <artifactId>swagger-models</artifactId>
        </exclusion>
    </exclusions>
</dependency>

<dependency>
    <groupId>io.swagger</groupId>
    <artifactId>swagger-models</artifactId>
    <version>1.5.21</version>
</dependency>
