解决swagger报错java.lang.NumberFormatException For input string “”

长话短说，导入这两个maven依赖即可解决

<!-- 处理swagger 报错：illegal defaultValue null for param type integer异常  -->
<dependency>
    <groupId>io.swagger</groupId>
    <artifactId>swagger-annotations</artifactId>
    <version>1.5.22</version>
</dependency>
<dependency>
    <groupId>io.swagger</groupId>
    <artifactId>swagger-models</artifactId>
    <version>1.5.22</version>
</dependency>

与此同时，我的swagger相关依赖分别为：

<!-- Swagger2 -->
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>3.0.0</version>
</dependency>

<!-- Knife4j -->
<dependency>
    <groupId>com.github.xiaoymin</groupId>
    <artifactId>knife4j-openapi2-spring-boot-starter</artifactId>
    <version>4.1.0</version>
</dependency>

界面：

springboot版本：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.7.11</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

导入maven依赖后，重新刷新，不会报错，完美解决。
