Example 1 with CascadingDataAccessStrategy

use of org.springframework.data.jdbc.core.convert.CascadingDataAccessStrategy in project spring-data-jdbc by spring-projects.

the class MyBatisDataAccessStrategy method createCombinedAccessStrategy.

/**
 * Create a {@link DataAccessStrategy} that first checks for queries defined by MyBatis and if it doesn't find one
 * uses a {@link DefaultDataAccessStrategy}
 */
public static DataAccessStrategy createCombinedAccessStrategy(RelationalMappingContext context, JdbcConverter converter, NamedParameterJdbcOperations operations, SqlSession sqlSession, NamespaceStrategy namespaceStrategy, Dialect dialect) {
    // the DefaultDataAccessStrategy needs a reference to the returned DataAccessStrategy. This creates a dependency
    // cycle. In order to create it, we need something that allows to defer closing the cycle until all the elements are
    // created. That is the purpose of the DelegatingAccessStrategy.
    DelegatingDataAccessStrategy delegatingDataAccessStrategy = new DelegatingDataAccessStrategy();
    MyBatisDataAccessStrategy myBatisDataAccessStrategy = new MyBatisDataAccessStrategy(sqlSession, dialect.getIdentifierProcessing());
