问题分析 #

日志明确显示，IdentityConfigParser在解析缓存配置时，试图将带时间单位的字符串"300ms"转换为整数，触发了NumberFormatException。该版本的WSO2 IS缓存配置仅接受纯数字（代表毫秒数），不支持带单位的格式。

解决步骤 #

• 定位配置文件：打开WSO2 IS安装目录下的repository/conf/identity/identity.xml文件。
• 查找错误配置：搜索包含"300ms"的配置项，这类配置通常属于缓存超时（如CacheTimeout）相关字段。
• 修正格式：将带单位的"300ms"改为纯数字300（若原本意图就是300毫秒），确保所有缓存相关配置值均为无单位的整数。
• 验证其他配置：遍历文件中所有缓存配置项，确认没有其他带时间单位的字符串格式值。
• 重启服务：保存修改后的配置文件，重新启动WSO2 Identity Server，检查启动是否正常。
