查看一下WildcardPermission.java源代码:
protected void setParts(String wildcardString, boolean caseSensitive) {
wildcardString = StringUtils.clean(wildcardString);
if(wildcardString != null && !wildcardString.isEmpty()) {
List parts = CollectionUtils.asList(wildcardString.split(":"));
this.parts = new ArrayList();
Iterator i$ = parts.iterator();
while(i$.hasNext()) {
String part = (String)i$.next();
Set subparts = CollectionUtils.asSet(part.split(","));
if(!caseSensitive) {
subparts = this.lowercase(subparts);
}
if(subparts.isEmpty()) {
throw new IllegalArgumentException("Wildcard string cannot contain parts with only dividers. Make sure permission strings are properly formatted.");
}
this.parts.add(subparts);
}
if(this.parts.isEmpty()) {
throw new IllegalArgumentException("Wildcard string cannot contain only dividers. Make sure permission strings are properly formatted.");
}
} else {
throw new IllegalArgumentException("Wildcard string cannot be null or empty. Make sure permission strings are properly formatted.");
}
}
因为不留神将空值插入到权限信息中，结果抛出以上异常。
去掉空值后正常。
