Static factory to retrieve a type 4 (pseudo randomly generated) UUID.

Usage

From source file:com.sample.serviceImpl.DonarsServiceImpl.java

@Override
public void save(Donars donar) {
    if (donar.getId() == null) {
        donar.setId(UUID.randomUUID() + "");
    }//  w  ww .j a va 2  s  .co m
    donarsRepository.save(donar);
}

From source file:com.univocity.examples.ExampleWithDatabase.java

protected JdbcDataStoreConfiguration newDatabaseConfiguration() {
    // The next three lines of code use some utility classes we created to easily
    // create and initialize in-memory databases for testing purposes.

    //creates an in-memory database with a random name and a directory with table definition scripts.
    DatabaseAccessor destinationConfig = new DatabaseAccessor(UUID.randomUUID().toString(), schemaDirPath);

    //initializes the database, creates all tables and returns a javax.sql.DataSource
    dataSource = destinationConfig.getDatabase().getDataSource();

    //Back to uniVocity, here we create a data store configuration for database entities.
    //It offers a lot of configuration options, but for this example, we will just need the following:

    //##CODE_START
    //Creates a new JDBC data store based on a javax.sql.DataSource, with the name "new_schema".
    //Upon initialization, uniVocity will try to auto-detect all available tables, columns and primary keys
    //If this doesn't work you still can configure each table manually.
    JdbcDataStoreConfiguration newSchemaDataStore = new JdbcDataStoreConfiguration(dataStoreName, dataSource);

    //The database contains lots of internal tables in addition to the tables we are interested in
    //By setting the schema to "public", these internal database tables won't be made available to uniVocity.
    newSchemaDataStore.setSchema("public");
    //##CODE_END//w ww  .j a  v  a  2 s  . c  om
    return newSchemaDataStore;
