我正在爲我的web + MVC +安全性（使用Spring 2.5，Spring安全2.0.4）使用JDBC模板進行角色用戶驗證在裏面。當我試圖去執行它，它給我以下錯誤：SQL JDBC模板下拉表問題：使用FK和唯一索引下拉表（JDBC模板）

HsqldbSchemaAndDataPopulator.java（JDBC模板）
public class HsqldbSchemaAndDataPopulator implements InitializingBean {
private JdbcTemplate template;
public void afterPropertiesSet() throws Exception {
Assert.notNull(template, "dataSource required");
// add tables to represent admin core-domain instances.
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);");
// add tables to represent bug tracking domain instances.
template
.execute("CREATE TABLE PROJECTS(ID BIGINT NOT NULL PRIMARY KEY, NAME VARCHAR_IGNORECASE(50) NOT NULL, DESCRIPTION VARCHAR_IGNORECASE(200) NOT NULL);");
// insert data here
template
.execute("INSERT INTO USERS VALUES('disabled','disabled',FALSE);");
template.execute("INSERT INTO USERS VALUES('admin','admin',TRUE);");
template
.execute("INSERT INTO USERS VALUES('username','password',TRUE);");
template.execute("INSERT INTO USERS VALUES('user','pass',TRUE);");
//ADMIN-ROLES
template
.execute("INSERT INTO AUTHORITIES VALUES('admin','ROLE_USER');");
template
.execute("INSERT INTO AUTHORITIES VALUES('admin','ROLE_ADMIN');");
//USER-ROLES
template
.execute("INSERT INTO AUTHORITIES VALUES('username','ROLE_USER');");
}
public void setDataSource(final DataSource dataSource) {
this.template = new JdbcTemplate(dataSource);
}
}
所以，我下面的代碼添加到HsqldbSchemaAndDataPopulator類：
//Delete tables if exist
template
.execute("ALTER TABLE AUTHORITIES DROP CONSTRAINT FK_AUTHORITIES_USERS;");
template
.execute("ALTER TABLE AUTHORITIES DROP INDEX IX_AUTH_USERNAME;");
template
.execute("DROP TABLE PROJECTS IF EXISTS;");
template
.execute("DROP TABLE USERS IF EXISTS;");
template
.execute("DROP TABLE USERS IF AUTHORITIES;");
現在，它給了我下面的錯誤：

這是我dataAccessContext.xml

我認爲我做錯了什麼與SQL語句，但不完全確定這是什麼？有人能幫我解決這個問題嗎？謝謝。
非常感謝fredt。 – AbdulAziz 2012-03-06 21:33:26
