spring security例程搭建（Mysql）
在Spring security2.0.4发布的包中，提供了，相应的例程，可是由于它缺省使用的并非Mysql数据库的问题，导致我们无法直接搭建起例程。如果要搭建起例程就需要修改SQL语句，使其适用于Mysql。现对，修改内容说明如下：
一：SQL语句的修改,修改DataSourcePopulator.java文件。
template.execute(
"CREATE TABLE ACL_SID(" +
"ID BIGINT GENERATED BY DEFAULT AS IDENTITY(START WITH 100) NOT NULL PRIMARY KEY," +
"PRINCIPAL BOOLEAN NOT NULL," +
"SID VARCHAR_IGNORECASE(100) NOT NULL," +
"CONSTRAINT UNIQUE_UK_1 UNIQUE(SID,PRINCIPAL));");
template.execute(
"CREATE TABLE ACL_CLASS(" +
"ID BIGINT GENERATED BY DEFAULT AS IDENTITY(START WITH 100) NOT NULL PRIMARY KEY," +
"CLASS VARCHAR_IGNORECASE(100) NOT NULL," +
"CONSTRAINT UNIQUE_UK_2 UNIQUE(CLASS));");
template.execute(
"CREATE TABLE ACL_OBJECT_IDENTITY(" +
"ID BIGINT GENERATED BY DEFAULT AS IDENTITY(START WITH 100) NOT NULL PRIMARY KEY," +
"OBJECT_ID_CLASS BIGINT NOT NULL," +
"OBJECT_ID_IDENTITY BIGINT NOT NULL," +
"PARENT_OBJECT BIGINT," +
"OWNER_SID BIGINT," +
"ENTRIES_INHERITING BOOLEAN NOT NULL," +
"CONSTRAINT UNIQUE_UK_3 UNIQUE(OBJECT_ID_CLASS,OBJECT_ID_IDENTITY)," +
"CONSTRAINT FOREIGN_FK_1 FOREIGN KEY(PARENT_OBJECT)REFERENCES ACL_OBJECT_IDENTITY(ID)," +
"CONSTRAINT FOREIGN_FK_2 FOREIGN KEY(OBJECT_ID_CLASS)REFERENCES ACL_CLASS(ID)," +
"CONSTRAINT FOREIGN_FK_3 FOREIGN KEY(OWNER_SID)REFERENCES ACL_SID(ID));");
template.execute(
"CREATE TABLE ACL_ENTRY(" +
"ID BIGINT GENERATED BY DEFAULT AS IDENTITY(START WITH 100) NOT NULL PRIMARY KEY," +
"ACL_OBJECT_IDENTITY BIGINT NOT NULL,ACE_ORDER INT NOT NULL,SID BIGINT NOT NULL," +
"MASK INTEGER NOT NULL,GRANTING BOOLEAN NOT NULL,AUDIT_SUCCESS BOOLEAN NOT NULL," +
"AUDIT_FAILURE BOOLEAN NOT NULL,CONSTRAINT UNIQUE_UK_4 UNIQUE(ACL_OBJECT_IDENTITY,ACE_ORDER)," +
"CONSTRAINT FOREIGN_FK_4 FOREIGN KEY(ACL_OBJECT_IDENTITY) REFERENCES ACL_OBJECT_IDENTITY(ID)," +
"CONSTRAINT FOREIGN_FK_5 FOREIGN KEY(SID) REFERENCES ACL_SID(ID));");
template.execute(
"CREATE TABLE USERS(USERNAME VARCHAR_IGNORECASE(50) NOT NULL PRIMARY KEY,PASSWORD VARCHAR_IGNORECASE(50) NOT NULL,ENABLED BOOLEAN NOT NULL);");
template.execute(
"CREATE TABLE AUTHORITIES(USERNAME VARCHAR_IGNORECASE(50) NOT NULL,AUTHORITY VARCHAR_IGNORECASE(50) NOT NULL,CONSTRAINT FK_AUTHORITIES_USERS FOREIGN KEY(USERNAME) REFERENCES USERS(USERNAME));");
template.execute("CREATE UNIQUE INDEX IX_AUTH_USERNAME ON AUTHORITIES(USERNAME,AUTHORITY);");
template.execute(
"CREATE TABLE CONTACTS(ID BIGINT NOT NULL PRIMARY KEY, CONTACT_NAME VARCHAR_IGNORECASE(50) NOT NULL, EMAIL VARCHAR_IGNORECASE(50) NOT NULL)");
上面代码需要修改如下内容：
引用
GENERATED BY DEFAULT AS IDENTITY(START WITH 100) NOT NULL PRIMARY KEY
改成：
引用
BIGINT NOT NULL AUTO_INCREMENT PRIMARY KEY
引用
VARCHAR_IGNORECASE
改成：
引用
VARCHAR
运行程序后仍然报错，是因为在spring-security-acl-2.0.4.jar包中有以下代码：
private String classIdentityQuery = "call identity()"; // should be overridden for postgres : sel
