Saiku数据库迁移H2迁移到mysql
Saiku默认使用H2数据库来存储saiku的用户与角色信息,我们可以根据角色来做saiku的权限控制,然后将角色分配给用户 ,该用户就会有对应的约束了!
由于项目即将上线,所以需要将数据库从H2迁移到公司的mysql数据库中。
需要更改的源码文件如下:
saiku-webapp项目下的配置文件:
/saiku-webapp/src/main/webapp/WEB-INF/web.xml
/saiku-webapp/src/main/webapp/WEB-INF/applicationContext-spring-security-jdbc.properties
/saiku-webapp/src/main/webapp/WEB-INF/saiku-beans.properties
saiku-service项目下的Java类:
/saiku-service/src/main/java/org/saiku/database/Database.java
1.更改 /saiku-webapp/src/main/webapp/WEB-INF/web.xml 文件中的参数
db.url db.user db.password
记得在10.22.33.44中新建数据库 saiku 哦!
<context-param> <param-name>db.url</param-name> <param-value>jdbc:mysql://10.22.33.44:3306/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.更改 /saiku-webapp/src/main/webapp/WEB-INF/applicationContext-spring-security-jdbc.properties 文件中的参数
jdbcauth.driver jdbcauth.url jdbcauth.username jdbcauth.password
jdbcauth.authoritiesquery=select username, role from user_roles where username =? UNION select \'?\', \\ \'ROLE_USER\' jdbcauth.usernamequery=select u.username,u.password, u.enabled from users u inner join ( \\ select MAX(USERS.USER_ID) ID, USERS.USERNAME from USERS group by USERS.USERNAME) tm on u.USER_ID =\\ tm.ID where u.username = ? GROUP BY u.USER_ID #jdbcauth.driver=org.h2.Driver #jdbcauth.url=jdbc:h2:../../data/saiku;MODE=MySQL #jdbcauth.username=sa #jdbcauth.password= jdbcauth.driver=com.mysql.jdbc.Driver jdbcauth.url=jdbc:mysql://10.22.33.44:3306/saiku?autoReconnect=true&useUnicode=true&characterEncoding=utf8 jdbcauth.username=root jdbcauth.password=root
3.更改 /saiku-webapp/src/main/webapp/WEB-INF/saiku-beans.properties 文件中的参数
userdao.driverclass userdao.url userdao.username userdao.password
default.role=ROLE_USER external.properties.file=${catalina.base}/conf/Catalina/localhost/datasources.properties webdav.password=sa!kuanalyt!cs #userdao.driverclass=org.h2.Driver #userdao.url=jdbc:h2:../../data/saiku;MODE=MySQL #userdao.username=sa #userdao.password= userdao.driverclass=com.mysql.jdbc.Driver userdao.url=jdbc:mysql://10.22.33.44:3306/saiku?autoReconnect=true&useUnicode=true&characterEncoding=utf8 userdao.username=root userdao.password=root logdir=../logs repoconfig=../../repository/configuration.xml repodata=../../repository/data foodmartrepo=../../data foodmartschema=../../data/FoodMart4.xml foodmarturl=jdbc:h2:../../data/foodmart;MODE=MySQL earthquakerepo=../../data earthquakeschema=../../data/Earthquakes.xml earthquakeurl=jdbc:h2:../../data/earthquakes;MODE=MySQL pluginpath=../webapps/ROOT/js/saiku/plugins/ orbis.auth.enabled=false workspaces=false repo.type=jackrabbit repo.host=localhost repo.port=8070 repo.username=admin repo.password=admin repo.database=saiku
4.更改 /saiku-service/src/main/java/org/saiku/database/Database.java 类中的方法,因为H2与mysql的语法会有些区别
4.1 更改 initDB() 方法
先将 private JdbcDataSource ds; 修改为 private MysqlDataSource ds; //将 JdbcDataSource 改为 MysqlDataSource
// private JdbcDataSource ds; //comment this line 20190412, for change the default database to mysql private MysqlDataSource ds; //add this line 20190412, for change the default database to mysql //for change the default database ,change h2 to mysql 2019-04-12 private void initDB() { String url = servletContext.getInitParameter("db.url"); String user = servletContext.getInitParameter("db.user"); String pword = servletContext.getInitParameter("db.password"); ds = new MysqlDataSource(); // 这里原来是 new JdbcDataSource(); ds.setUrl(url); ds.setUser(user); ds.setPassword(pword); }
4.2 更改 loadUsers() 方法
//for change the default database ,change h2 to mysql 2019-03-06 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(); } }
4.3 更改 checkUpdatedEncyption() 方法
//for change the default database ,change h2 to mysql 2019-03-06 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; }
4.4 更改 updateForEncyption() 方法
//for change the default database ,change h2 to mysql 2019-03-06 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\');"); }
4.4 更改 init() 方法 注释掉 loadFoodmart() 方法与 loadEarthquakes()方法
public void init() throws SQLException { initDB(); loadUsers(); // loadFoodmart(); // loadEarthquakes(); loadLegacyDatasources(); importLicense(); }
以上修改都完成后,可以重新打包编译Saiku了,启动saiku,访问saiku,再回到数据库中就会看到数据库中已经建好了三张表了
user 存储用户以及密码信息
log 存储日志信息
user_roles 存储用户与角色的关系信息
然后接着我们可以试试使用admin登录saiku ,新增用户以及删除用户信息。
不知道为什么第一次我编译成功后,登录saiku想去新增用户,但是新增用户接口没有调通,删除用户接口也报错 NullPointerException
后来我再一次重新打包编译saiku源码,再去访问就又OK了,新增与删除都没有问题!!! 新增的用户也会存到我们定义的saiku库中,删除时数据也会被删除。权限配置好后也是ok的,一切都能正常使用!
至此 saiku数据库从H2到mysql 迁移成功啦!!!
