模型映射器异常：仅在Docker中无法将java.lang.String转换为java.lang.Integer

如何解决模型映射器异常：仅在Docker中无法将java.lang.String转换为java.lang.Integer

将DTO转换为实体时，我面临NumberFormatException。尽管我在DTO和Entity中遇到异常的字段都是String。

奇怪的是，仅当我在docker上部署应用程序时，我才得到该异常。如果我以独立方式运行应用程序，那么一切都很好。

下面是我的代码

UserDTO：

@JsonInclude(JsonInclude.Include.NON_NULL)
public class UserDto {
   private Integer userId;

   private String displayCode;

   private String firstName;

   private String lastName;

   private String username;

   private String password;

   private String email;

   private String phone;

   private String photo;

   private Short title;

   private String npi;

   private List<Integer> postNominal;

   @JsonProperty("isDoctor")
   private Boolean isDoctor;

   private Integer userType;

   private Boolean active;

   private Boolean agreementActive;

   private String accessCode;

   private Integer createdBy;

   private Timestamp createdTimestamp;

   private Integer updatedBy;

   private Timestamp updatedTimestamp;

   private List<RoleDto> roles;

   private Integer departmentId;

   private UserDto reportingTo;

   @JsonIgnore
   private String partnerdisplayCode;

   @JsonProperty("userRoles")
   private String userRole;

   private String  base64Image;

   getters...
   setters...

}

UserEntity：

 @Entity
 @Table(name = "user",schema = "user_management")
 public class UserEntity extends BaseEntity implements Serializable {
     private static final long serialVersionUID = 1L;

     @Id
     @GeneratedValue(strategy = GenerationType.IDENTITY)
     @Column(name = "user_id")
     private Integer userId;

     @Column(name = "display_code")
     private String displayCode;

     @Column(name = "user_type")
     private Short userType;

     @Column(name = "first_name")
     private String firstName;

     @Column(name = "last_name")
     private String lastName;

     @Column(name = "username")
     private String username;

     @Column(name = "password")
     private String password;

     @Column(name = "email")
     private String email;

     @Column(name = "phone")
     private String phone;

     @Column(name = "photo")
     private String photo;

     @Column(name = "title")
     private Short title;

     @Column(name = "npi")
     private String npi;

     @Column(name = "department_id")
     private Integer departmentId;

     @Column(name = "is_doctor")
     private Short isDoctor;

     @Column(name = "agreement_active")
     private Short agreementActive;

     @Column(name = "access_code")
     private String accessCode;

     @Column(name = "status")
     private Short active;

     getters ....
     setters
 }

UserService类：

@Override
@Transactional
public UserDto persist(UserWithDependenciesDto user) {
    modelmapper.getConfiguration().setSkipNullEnabled(true);
    modelmapper.addConverter(CommonUtil.BOOLEAN_SHORT_CONVERTER);
    UserEntity userEntity = modelmapper.map(user.getUser(),UserEntity.class);
     ....
}

@postconstruct
public void initializemodelmapperStrategy() {
    this.modelmapper.getConfiguration().setAmbiguityIgnored(true);
    this.modelmapper.getConfiguration()
                      .setMatchingStrategy(MatchingStrategies.STRICT);
}

UserWithDependenciesDto：

 public class UserWithDependenciesDto {
      @JsonProperty("partnerId")
      private Integer partnerId;
      @JsonProperty("user")
      private  UserDto user;
      @JsonProperty("createdBy")
      private  Integer createdBy;
     .... 
 }

        },{
           "createdBy":1,"roleUId":3,"name":"CRM","isPhysician":true
        }
     ],"isDoctor":false
  },"createdBy":1

} }

我在UserDto和Entity中的AccessCode上遇到数字格式异常。您将在两边都看到它是String。

解决方法

好的，这是非常有线的。模型映射器以某种方式将其策略从“严格”更改为“宽松”。尽管在后期构造中，到达目标对象的绘制位置时严格，但策略是宽松的。

所以我要做的是删除后构造注释，并在发生转换的地方调用该方法。因此在转换过程中，该策略变得严格，上述问题得以解决。
