Question

I am trying to insert a file from a java application into a mysql table.

The call to the mapper completes without any exception, but at the end I don’t find any records inside the table.

Maybe there is something wrong with the way I am mapping a file content to the blob field?

This is the bean:

public class CustomFile {
private int id;
private String title;
private String fileName;
private String fileType;
private String fileSize;
private byte[] fileContent;
private String fileExtension;

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public String getTitle() {
    return title;
}

public void setTitle(String title) {
    this.title = title;
}

public String getFileName() {
    return fileName;
}

public void setFileName(String fileName) {
    this.fileName = fileName;
}

public String getFileType() {
    return fileType;
}

public void setFileType(String fileType) {
    this.fileType = fileType;
}

public String getFileSize() {
    return fileSize;
}

public void setFileSize(String fileSize) {
    this.fileSize = fileSize;
}

public byte[] getFileContent() {
    return fileContent;
}

public void setFileContent(byte[] fileContent) {
    this.fileContent = fileContent;
}

public String getFileExtension() {
    return fileExtension;
}

public void setFileExtension(String fileExtension) {
    this.fileExtension = fileExtension;
}

 }

And this is the mapping:

<insert id="saveFile" parameterType="CustomFile">

    INSERT INTO file SET
    Title = #{title},
    File_Name = #{fileName},
    File_Type = #{fileType},
    File_Size = #{fileSize},
    File_Content = #{fileContent,jdbcType=BLOB},
    File_Extension = #{fileExtension}

</insert>

this is the log4j log:

Thanks!

Perhaps you are failing to commit your insert? May we see the code where you create the SqlSession?
