# # java.lang.NumberFormatException: For input string: ""

很多朋友在升级Springfox-Swagger到2.9.2版本后会碰见NumberFormatException异常java.lang.NumberFormatException: For input string: ""

异常信息如下：

    java.lang.NumberFormatException: For input string: ""
    	at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65) ~[na:1.8.0_111]
    	at java.lang.Long.parseLong(Long.java:601) ~[na:1.8.0_111]
    	at java.lang.Long.valueOf(Long.java:803) ~[na:1.8.0_111]
    	at
    	//more....

解决办法是在pom.xml中排除Springfox-Swagger的Swagger-Models的jar包,重新引入，如下：

    <!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger2 -->
    <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>

    <!-- https://mvnrepository.com/artifact/io.swagger/swagger-models -->
    <dependency>
        <groupId>io.swagger</groupId>
        <artifactId>swagger-models</artifactId>
        <version>1.5.21</version>
    </dependency>
