以下是具有实体类的两个表.

tbl_rules

| rule_id | rule_name |

    @Entity
    @Table(name = "db_user_name.tbl_rules")
    public class Rule implements Serializable {
        private static final long serialVersionUID = 1L;

        @Id
        @Basic(optional = false)
        @GenericGenerator(name = "incre", strategy = "increment")
        @GeneratedValue(generator = "incre")
        @Column(name = "rule_id", unique = true, nullable = false)
        private long ruleId;

        @Column(name = "rule_name", length = 250)
        private String ruleName;

        @OneToMany(fetch = FetchType.LAZY, mappedBy = "rules")
        private Set<Benchmark> benchmarks = new HashSet<Benchmark>(0);
        ... getters and setters
    }

tbl_benchmark

| benchmark_id | rule_id …
