mybatis 设置新增数据后返回自增主键

1. 主要是注解@Options起作用，语句如下：

    @Insert({
            "INSERT INTO application_open_up ( " +
                    "app_open_hospital_id, " +
                    "application_id, " +
                    "service_time, " +
                    "createdby, " +
                    "createdon, " +
                    "modifiedby, " +
                    "modifiedon, " +
                    "deletion_state, " +
                    "purchase_price, " +
                    "config_id, " +
                    "meta_url " +
                    ") " +
                    "VALUES (" +
                    "#{appOpenHospitalId}, " +
                    "#{applicationId}, " +
                    "#{serviceTime}, " +
                    "#{createby}, " +
                    "#{createon}, " +
                    "#{modifiedby}, " +
                    "#{modifiedon}, " +
                    "#{deletionState}, " +
                    "#{purchasePrice}, " +
                    "#{configId}, " +
                    "#{metaUrl}) "})
    @Options(useGeneratedKeys = true, keyProperty = "id")
    void save(PApplicationOpenUp pApplicationOpenUp);

2. 另一种形式，在实体类的主键上加上注解： @Id 与 @GeneratedValue(generator = "JDBC")，如下所示：

    @Id
    @ApiModelProperty(value = "自增主键")
    @Column(name = "interface_regular_id")
    @GeneratedValue(generator = "JDBC")
    private Integer interfaceRegularId;
