环境搭建

属性类

PhoneNumber

@Builder
@Data
@NoArgsConstructor
@AllArgsConstructor
public class PhoneNumber {

    private String code;

    private String number;

    /**
     * 序列化格式
     * @return
     */
    @Override
    public String toString() {
        return code + "-" + number;
    }
}

实体类

@Data
@ToString
@Builder
@TableName("t_project")
@NoArgsConstructor
@AllArgsConstructor
public class Project {
    @Id
    private Long id;

    private PhoneNumber phoneNumber;

反序列化转换

@Component
final public class StringToPhoneNumberConverterFactory implements ConverterFactory<String, PhoneNumber> {

    @Override
    public <T extends PhoneNumber> Converter<String, T> getConverter(Class<T> aClass) {
        return new StringToPhoneNumber();
    }

    private static class StringToPhoneNumber<T> implements Converter<String, T> {

        @Override
        public T convert(String source) {
            if (StringUtils.isBlank(source)) {
                return null;
            }

            String[] arr = source.split("-");
            return (T) PhoneNumber.builder().code(arr[0]).number(arr[1]).build();
        }
    }

}

测试

@Test
public void testSave() {
    Project project = new Project();

    project.setPhoneNumber("861-18888888888");

    projectDAO.insert(project);
    Assert.assertNotNull(project.getId());
}

@Test
public void testFindById() {
    Optional<Project> optional = projectDAO.selectById(479411923147194368L);
    Project project = optional.get();

    Assert.assertEquals("18888888888", project.getPhoneNumber().getNumber());
}
