我使用Spring ACL和MySQL一起工作正常。然而，當集成測試我使用HSQLDB引擎，當我打電話aclService.updateAcl(myAcl)它拋出以下異常（S）：更新ACL時JdbcMutableAclService + HSQLDB = BadSqlGrammarException
Caused by: org.springframework.jdbc.BadSqlGrammarException:
PreparedStatementCallback; bad SQL grammar
[insert into acl_entry (acl_object_identity, ace_order, sid, mask, granting,
audit_success, audit_failure)values (?, ?, ?, ?, ?, ?, ?)]; nested exception is
java.sql.SQLException: statement is not in batch mode
...
java.sql.SQLException: statement is not in batch mode
...
org.hsqldb.HsqlException: statement is not in batch mode
整個代碼片段：
ObjectIdentity oi = new ObjectIdentityImpl(domainObject);
MutableAcl acl = aclService.createAcl(oi);
acl.setOwner(new PrincipalSid(SYSTEM_PRINCIPAL_SID));
if (parentObject != null) {
Acl parent = aclService.readAclById(new ObjectIdentityImpl(parentObject));
acl.setParent(parent);
}
aclService.updateAcl(acl);
的aclService場的情況下類JdbcMutableAclService。請注意，在MySQL上一切正常。
Spring 3.1.2.RELEASE。
編輯： 其實異常被拋出只有當acl.getEntries()返回空列表（ACL中剛剛創造的 - 它不包含任何的ACE）。我通過擴展JdbcMutableAclService的默認實現並通過在空列表上調用createEntries()來覆蓋導致此問題的updateAcl()方法來解決此問題。我仍然不知道這個問題的真正原因，但我設法讓它工作。這裏是我快速的解決方案：
@Override
public MutableAcl updateAcl(MutableAcl acl) throws NotFoundException {
if (acl.getEntries().size() > 0) {
return super.updateAcl(acl);
}
Assert.notNull(acl.getId(), "Object Identity doesn't provide an identifier");
// Change the mutable columns in acl_object_identity
updateObjectIdentity(acl);
// Retrieve the ACL via superclass (ensures cache registration, proper retrieval etc)
return (MutableAcl)super.readAclById(acl.getObjectIdentity());
}
