Saiku数据库迁移H2迁移到Mysql(二十二)
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！！！
