Question

我在我的代码中有这个查询。我试图在最后一栏（blob）中将图像归入表格。它显示无效的十六进制数。任何人都能帮我解决这个问题吗？

 @ManagedBean(name="userprofile",eager=true)
 @SessionScoped
 public class Profile {

 @ManagedProperty("#{jdbcTemplate}")
public JdbcTemplate jdbcTemplate;
    private String firstName,lastName,email,description;
    private UploadedFile photo1;
    private int contactNumber;
private String insertQry;


public JdbcTemplate getJdbcTemplate() {
    return jdbcTemplate;
}

public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
    this.jdbcTemplate = jdbcTemplate;
}
    public UploadedFile getPhoto1() {
return photo1;
    }

    public void setPhoto1(UploadedFile photo1) {
 this.photo1 = photo1;
    }

    public String getEmail() {
return email;
    }

    public void setEmail(String email) {
this.email = email;
    }

    public String getDescription() {
return description;
    }
    public void setDescription(String description) {
this.description = description;
     }

    public String getFirstName() {
return firstName;
    }
    public void setFirstName(String firstName) {
this.firstName = firstName;
    }

    public String getLastName() {
return lastName;
    }
    public void setLastName(String lastName) {
this.lastName = lastName;
    }

    public int getContactNumber() {
return contactNumber;
    }

     public void setContactNumber(int contactNumber) {
  this.contactNumber = contactNumber;
     }

     public void insertProfile() throws Exception{

 InputStream is=photo1.getInputstream();
 System.out.println(is);
 insertQry="insert into profile   
               values('"+getFirstName()+"','"+getLastName()+"','"+getContactNumber()+"',
               '"+getEmail()+"','"+getDescription()+"','"+utl_raw.cast_to_raw(is)+"')";
 System.out.println(insertQry);



int num=jdbcTemplate.update(insertQry);
System.out.println(num);

   }

   }

任何形式的回应都会提前得到赞赏。

此错误：

 invalid hex number ora-01465

表示您不发送Hexa。

<强>解决方案：

请在插入图片之前尝试将InputStream转换为Hexa。

无效的十六进制数ora-01465
