 | 1 ffkjjj Dec 24, 2019 via iPhone This is very likely to create a memory leak. 是不是内存空间不足了… |
 | 2 vanishxiaoma OP @ffkjjj 是有个请求地址重复了 , 但是异常没有报 , 这架构师说不知道哪里的问题 , 经过排查 少了 spring-security-core 这个 jar 包 |
| 3 vanishxiaoma OP @ffkjjj 加上这个 jar 包 错误信息才打印出来 |
 | 4 DJQTDJ Dec 24, 2019 server.xml 里将监听器注释掉？ |
