saiku數據庫的表和用戶默認創建是在啟動項目的時候,通過初始化 saiku-beans.xml 中的 h2database 這個 bean
執行org.saiku.service.Database類的init方法來初始化數據表和默認用戶的。
具體修改如下:
1/修改web.xml 中 數據連接配置信息
將數據庫鏈接修改為本地mysql配置信息:
<context-param> <param-name>db.url</param-name> <param-value>jdbc:mysql://localhost:3306/saiku</param-value> </context-param> <context-param> <param-name>db.user</param-name> <param-value>root</param-value> </context-param> <context-param> <param-name>db.password</param-name> <param-value>root</param-value> </context-param>
2/修改saiku-beans.xml中h2database配置信息
新增mysql數據源適配:
<bean id="h2database" class="org.saiku.database.Database" init-method="init"> <property name="datasourceManager" ref="repositoryDsManager"/> <property name="datasourcetype" value="mysql" /> </bean>
3/修改Database中獲取的數據源為mysql
修改Database類:
private String datasourcetype = "mysql";
private void initDB() { String url = servletContext.getInitParameter("db.url"); String user = servletContext.getInitParameter("db.user"); String pword = servletContext.getInitParameter("db.password"); if (this.datasourcetype.equals("mysql")) { ds = new MysqlDataSource(); ((MysqlDataSource) ds).setUrl(url); ((MysqlDataSource) ds).setUser(user); ((MysqlDataSource) ds).setPassword(pword); } else if (this.datasourcetype.equals("h2")) { ds = new JdbcDataSource(); ((JdbcDataSource) ds).setUrl(url); ((JdbcDataSource) ds).setUser(user); ((JdbcDataSource) ds).setPassword(pword); } }
4/因為h2建表sql和mysql的還是有差異的,所以將創建表和用戶信息的代碼替換如下:
mysql數據表和用戶的創建代碼為:
private void loadUsers() throws SQLException { Connection c = ds.getConnection(); Statement statement = c.createStatement(); statement.execute(" CREATE TABLE IF NOT EXISTS log ( time TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP, log TEXT); "); statement.execute(" CREATE TABLE IF NOT EXISTS users(user_id INT(11) NOT NULL AUTO_INCREMENT, " + " username VARCHAR(45) NOT NULL UNIQUE, password VARCHAR(100) NOT NULL, email VARCHAR(100), " + " enabled TINYINT NOT NULL DEFAULT 1, PRIMARY KEY(user_id)); "); statement.execute(" CREATE TABLE IF NOT EXISTS user_roles ( " + " user_role_id INT(11) NOT NULL AUTO_INCREMENT,username VARCHAR(45), " + " user_id INT(11) NOT NULL REFERENCES users(user_id), " + " ROLE VARCHAR(45) NOT NULL, " + " PRIMARY KEY (user_role_id)); "); ResultSet result = statement.executeQuery("select count(*) as c from log where log = 'insert users'"); result.next(); if (result.getInt("c") == 0) { statement.execute("INSERT INTO users (username,password,email, enabled) VALUES ('admin','admin', 'test@admin.com',TRUE);"); statement.execute("INSERT INTO users (username,password,enabled) VALUES ('smith','smith', TRUE);"); statement.execute("INSERT INTO user_roles (user_id, username, ROLE) VALUES (1, 'admin', 'ROLE_USER');"); statement.execute("INSERT INTO user_roles (user_id, username, ROLE) VALUES (1, 'admin', 'ROLE_ADMIN');"); statement.execute("INSERT INTO user_roles (user_id, username, ROLE) VALUES (2, 'smith', 'ROLE_USER');"); statement.execute("INSERT INTO log (log) VALUES('insert users');"); } String encrypt = servletContext.getInitParameter("db.encryptpassword"); if (encrypt.equals("true") && !checkUpdatedEncyption()) { updateForEncyption(); } } public boolean checkUpdatedEncyption() throws SQLException{ Connection c = ds.getConnection(); Statement statement = c.createStatement(); ResultSet result = statement.executeQuery("select count(*) as c from log where log = 'update passwords'"); result.next(); return result.getInt("c") != 0; } public void updateForEncyption() throws SQLException { Connection c = ds.getConnection(); Statement statement = c.createStatement(); statement.execute("ALTER TABLE users MODIFY COLUMN PASSWORD VARCHAR(100) DEFAULT NULL"); ResultSet result = statement.executeQuery("select username, password from users"); while (result.next()) { statement = c.createStatement(); String pword = result.getString("password"); String hashedPassword = passwordEncoder.encode(pword); String sql = "UPDATE users " + "SET password = '" + hashedPassword + "' WHERE username = '" + result.getString("username") + "'"; statement.executeUpdate(sql); } statement = c.createStatement(); statement.execute("INSERT INTO log (log) VALUES('update passwords');"); }
以上的信息修改完畢后,在本地mysql創建url中指定的database->saikuBase,此時db中無任何表
運行saiku項目成功后,刷新db,可以看見db中多出了三張表user/user_roles/log,說明初始化表和默認數據已經成功。
但是,此時只是創建了表結構和默認的登陸賬戶,並沒有修改登錄的用戶認證數據源。
當我們使用admin登陸時還是會訪問到jdbc中配置的h2數據庫數據源。
其實這時候還是通過訪問h2內嵌數據庫的db文件登陸的,在管理端新建的用戶也會保存在h2數據源中,mysql數據源中查詢不到新建的用戶
所以,接下來要修改認證數據源為本地的mysql
5/修改用戶認證數據源
將 bean id 為 datasource 的 數據源的配置信息改為我們本地mysql的配置信息,重新部署服務並啟動
這時,我們在管理端創建一個用戶saiku,點擊保存。
查看本地mysql數據庫的user表,能看見saiku已經存在user表中了,並且使用saiku用戶登錄也能登錄成功。
將*security-jdbc.xml 中的配置信息改成mysql的即可
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" > <property name="driverClassName" value="mysql的驅動"/> <property name="url" value="mysql的url"/> <property name="username" value="賬戶名"/> <property name="password" value="密碼"/>
</bean>
至此就完成了h2數據庫遷移到本地mysql的操作了
