试图将数据从 servlet 发送到 java，但有映射错误

如何解决试图将数据从 servlet 发送到 java，但有映射错误

我正在使用 servlet，并尝试将数据从 html 发送到 Java 应用程序。然后返回数据。 我遇到了一个错误。

Cannot deserialize value of type `int` from Object value (token `JsonToken.START_OBJECT`)
 at [Source: (String)"{"reimb_type_id":{},"reimb_amount":{},"reimb_description":null}"; line: 1,column: 18] (through reference chain: com.revature.models.ReimbursementsDTO["reimb_type_id"])

它所说的代码，它来自：

public int reim_id;
    
    public int reimb_type_id;
    
    public int reimb_status_id;
    
    public int reimb_amount;
    
    public String reimb_description;
    
    public ReimbursementsDTO(int reimb_status_id) {
        super();
        this.reimb_status_id = reimb_status_id;
    }
    
    public ReimbursementsDTO(int reim_id,int reimb_status_id) {
        super();
        this.reim_id = reim_id;
        this.reimb_status_id = reimb_status_id;
    }
    
    public ReimbursementsDTO() {
        super();
    }

    public ReimbursementsDTO(int reimb_type_id,int reimb_amount,String reimb_description) {
        super();
        this.reimb_type_id = reimb_type_id;
        this.reimb_amount = reimb_amount;
        this.reimb_description = reimb_description;
    }
     ```

I tried to pass in values into a method but encountered this problem every single time.

public void submitReimbursements(int reimb_type_id,String reimb_description) {

    try(Connection connection = ConnectionUtil.getConnection()) {
        
        ResultSet resultSet = null; // intialize an empty resultset that will store the results of our query.
        //sql statement to get all of the info from reimbursement
        String sql = "INSERT into \"P1\".reimbursements"
                + "(reimb_amount,reimb_submitted,reimb_resolved,reimb_description,"
                + "reimb_author,reimb_resolver,reimb_status_id,reimb_type_id)"
                + "values (?,?,null,1,2,?);";
        
        
        java.sql.Statement statement = connection.createStatement();
        
        PreparedStatement preparedStatement = connection.prepareStatement(sql); 
    
        
        preparedStatement.setInt(1,reimb_type_id);
        preparedStatement.setInt(2,reimb_amount );
        preparedStatement.setString(3,reimb_description );

//preparedStatement.setInt(4,0);

        statement.executeQuery(sql);
    
    }catch (Exception e) {
    // TODO: handle exception
}
    

}
