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：

  1. java.lang.NumberFormatException: For input string: ""
  2. at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65) ~[na:1.8.0_111]
  3. at java.lang.Long.parseLong(Long.java:601) ~[na:1.8.0_111]
  4. at java.lang.Long.valueOf(Long.java:803) ~[na:1.8.0_111]
  5. at
  6. //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：

  2. <dependency>
  3. <groupId>io.springfox</groupId>
  4. <artifactId>springfox-swagger2</artifactId>
  5. <version>2.9.2</version>

  9. <artifactId>swagger-models</artifactId>
  10. </exclusion>
  11. </exclusions>
  12. </dependency>
