#Convert(converter = MsisdnEncryptor.class,disableConversion=true)
I have used this converter in my spring boot entity class.
package com.example.demo.entity;
This is the entity class:
#Entity
#Data
#AllArgsConstructor
#NoArgsConstructor
#Table(name="employee")
public class Employee {
#Id
#Column(name = "emp_id")
#SequenceGenerator(
name = "employee_sequence",
sequenceName = "employee_sequence",
allocationSize = 1
)
#GeneratedValue(strategy = GenerationType.SEQUENCE,
generator = "employee_sequence")
private Long EmpId;
#Column(name = "first_name")
private String firstName;
#Column(name = "last_name")
private String lastName;
#Column(name = "mobile_number")
**#Convert(converter = MsisdnEncryptor.class,disableConversion=true)**
**here I want to put values from application.properties in disableConversion**
private String mobileNumber;
#Column(name= "date_time")
#JsonFormat(shape=JsonFormat.Shape.STRING, pattern="dd-MM-yyyy HH:mm:ss", timezone="GMT+5:30")
private Timestamp dateTime;
}
This is the Encryptor class:
#Component
public class MsisdnEncryptor implements AttributeConverter<String, String> {
private static final Logger logger = LoggerFactory.getLogger(MsisdnEncryptor.class);
#Value("${is.enabled:true}")
private boolean isEnabled;
private static final String AES = "AES";
private static final String SECRET = "secret-key-12345";
private final Key key;
private final Cipher cipher;
public MsisdnEncryptor() throws Exception {
key = new SecretKeySpec(SECRET.getBytes(), AES);
cipher = Cipher.getInstance(AES);
}
#Override
public String convertToDatabaseColumn(String attribute) {
try {
cipher.init(Cipher.ENCRYPT_MODE, key);
return Base64.getEncoder().encodeToString(cipher.doFinal(attribute.getBytes()));
} catch (IllegalBlockSizeException | BadPaddingException | InvalidKeyException e) {
throw new IllegalStateException(e);
}
}
#Override
public String convertToEntityAttribute(String dbData) {
try {
cipher.init(Cipher.DECRYPT_MODE, key);
return new String(cipher.doFinal(Base64.getDecoder().decode(dbData)));
} catch (InvalidKeyException | BadPaddingException | IllegalBlockSizeException e) {
throw new IllegalStateException(e);
}
}
}
I know we can use #Value for taking the values , but it doesn't work here as it says attribute value must be constant.
Or if there is any other way of doing the encryption and enabling/disabling it from config , I would be more than happy to go through it.
I'm using a Thymeleaf HTML registration form and simple save/update method to save/update a 'dish' object to a mySQL database. Restaurant Id is a foreign key for the 'dish' but using the below methods it saves as 'null',
I would like to make it so that the Restaurant id of the currently logged in restaurant owner saves automatically when they add a dish.
Is there an uncomplicated way to do this? The closest tutorial I've found on Youtube involves using JSON requests in Postman and I've had issue adapting that to a HTML registration form in the past.
I'm quite new to all of this so any help would be very much appreciated!

Can you make sure Dish's "app" attribute is being set correctly before trying to save it?
If it's null or it's a brand new instance of AppUser class it makes sense that when trying to match and persist it ends up on null.
Greetings!
I am new to DynamoDB and wanted to know how can we query on a table in DynamoDB by using ONLY partition key in JAVA
I have table called "ervive-pdi-data-invalid-qa" and it's Schema is :
partition key is "SubmissionId"
Sort key is "Id".
City (Attribute)
Errors (Attribute)
The table looks like this:
Table
I want to retrieve the sort key value and remaining attributes data by using Partition key using (software.amazon.awssdk) new version of AWS SDK DynamoDB classes.
is it possible to get it? If so, can any one post the answers?
Have tried this:
DynamoDbClient ddb =
DynamoDbClient.builder().region(Region.US_EAST_1).build();
DynamoDbEnhancedClient enhancedClient =
DynamoDbEnhancedClient.builder()
.dynamoDbClient(ddb)
.build();
//Define table
DynamoDbTable<ErvivePdiDataInvalidQa> table =
enhancedClient.table("ervive-pdi-data-invalid-qa",
TableSchema.fromBean(ErvivePdiDataInvalidQa.class));
Key key = Key.builder().partitionValue(2023).build();
ErvivePdiDataInvalidQa result = table.getItem(r->r.key(key));
System.out.println("The record id is "+result.getId());
ErvivePdiDataInvalidQa table class is in below comment*
and it is returning "The provided key element does not match the schema (Service: DynamoDb, Status Code: 400, Request ID: PE1MKPMQ9MLT51OLJQVDCURQGBVV4KQNSO5AEMVJF66Q9ASUAAJG, Extended Request ID: null)"
Query you need is documented in one of the examples of AWS Dynamodb Query API for Java.
AmazonDynamoDB client = AmazonDynamoDBClientBuilder.standard()
.withRegion(Regions.US_WEST_2).build();
DynamoDB dynamoDB = new DynamoDB(client);
Table table = dynamoDB.getTable("ervive-pdi-data-invalid-qa");
QuerySpec spec = new QuerySpec()
.withKeyConditionExpression("SubmissionId = :v_id")
.withValueMap(new ValueMap()
.withInt(":v_id", 2146));
ItemCollection<QueryOutcome> items = table.query(spec);
Iterator<Item> iterator = items.iterator();
Item item = null;
while (iterator.hasNext()) {
item = iterator.next();
System.out.println(item.toJSONPretty());
}
A single Query operation can retrieve a maximum of 1 MB of data, see documentation
I have been working with Padma on this issue. We first tried A. Khan's code but could not get passed authentication with v1. Instead we got "WARNING: Your profile name includes a 'profile ' prefix. This is considered part of the profile name in the Java SDK, so you will need to include this prefix in your profile name when you reference this profile from your Java code."
ultimately it could not get the credentials. Our credentials assume IAM roles in .aws/config-i2 file. It works fine in v2 but not v1.
So then we tried v2 of the SDK and have no problems with connecting but we get NULL returned on trying to fetch all records from the table.
In all of the below attempts using v2 of SDK, table data returns NULL
We created this table class

I hade a strange happening today with my Firebase project.
Suddenly the
AddressChatMessage chatMessage = snapshot.getValue(AddressChatMessage.class);
parsed everything ok for the AddressChatMessage except for one int.
Took me 2 hour until i tried this, setting the field to public
public int type;
Note I use this code for weeks without problem and today Android studio made some core updated to 2.3.2 and maybe that trigger this strange event.
Here´s the AddressChatMessage.java nothing strange except that the public int type cannot be private, if it is, it will be zero, that too is strange, usually Firebase give out a logcat warning when pojo parsing fails. I have 10 other modell classes like this with plenty of int´s

When cleaning the code using Lint. Lint suggested changes like "This can be private instead of public" - I accidentally set the getType() to private access.
I am using JBoss 7.1.Final as application server and Oracle as database. We are using Spring framework 3.x and Java 6. trying to pass in an array of Strings and convert them inside the stored proc to array of varchars. I haven't found a good example for this yet. Please provide a pointer if you can to any documentation or previous forum post. I have searched and not found one that seems to apply.
The stored proc is defined as:
CREATE OR REPLACE PROCEDURE GET_TEST_CONTENTS
(IN_RR_ARRAY IN RR_ARRAY,
IN_ORDER_STATE IN VARCHAR2,
OUT_FLAG OUT VARCHAR2,
OUT_RETURN_CODE OUT VARCHAR2,
OUT_RETURN_DESC OUT VARCHAR2,
OUT_RETURN_TYPE OUT VARCHAR2,
OUT_RETURN_VAL OUT NUMBER
)
Type RR_ARRAY is defined as:
create or replace
type RR_ARRAY as table of varchar2(15);
Within my java code I have:
jdbcTemplate = new JdbcTemplate(dataSource);
jdbcTemplate.setResultsMapCaseInsensitive(true);
this.getTestContents = new SimpleJdbcCall(jdbcTemplate)
.withCatalogName("STAR")
.withoutProcedureColumnMetaDataAccess()
.withProcedureName("GET_TEST_CONTENTS")
.declareParameters(
new SqlParameter("IN_RR_ARRAY", OracleTypes.ARRAY,
"RR_ARRAY"),
new SqlParameter("IN_ORDER_STATE", OracleTypes.VARCHAR), new SqlOutParameter("OUT_FLAG",
OracleTypes.VARCHAR),
new SqlOutParameter("OUT_RETURN_VAL", OracleTypes.INTEGER),
new SqlOutParameter("OUT_RETURN_CODE", OracleTypes.VARCHAR),
new SqlOutParameter("OUT_RETURN_DESC", OracleTypes.VARCHAR),
new SqlOutParameter("OUT_RETURN_TYPE", OracleTypes.VARCHAR));
//I get a different error here so creating new connection for testing
//conn = jdbcTemplate.getDataSource().getConnection();
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
conn = DriverManager.getConnection(jdbcURL, user, passwd);
ArrayDescriptor desc = new ArrayDescriptor("STAR.RR_ARRAY", conn);

I found the fix for this. Now I use this List of Strings:
List<String> ndcList;
I changed the array parameter from OracleTypes.ARRAY to java.sql.stypes.ARRAY and specified schema prefix on array name. And changed the code and created a few new convenience methods at the bottom.
I needed the wrapped connection and had to add this dependency to my pom:
<dependency>
<groupId>jboss</groupId>
<artifactId>jboss-common-jdbc-wrapper</artifactId>
<version>3.2.3</version>
</dependency>

Here's code backup, in case page will be unavailable:

I looked at the internet and it was very difficult to get it working with the solution many people have provided.. here is working code example.. in pom.xml create this dependency.
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-oracle</artifactId>
<version>2.0.0.M1</version>
</dependency>
oracle sample code
create table employee (EMPNO number(12) not null, FNAME varchar2(60), LNAME varchar2(60), EMAIL varchar2(120));
CREATE SEQUENCE empno_seq START WITH 1 INCREMENT BY 1 NOCACHE NOCYCLE;
CREATE OR REPLACE TYPE employee_type
AS OBJECT (EMPNO number(12), FNAME varchar2(60), LNAME varchar2(60), EMAIL varchar2(120));
/
CREATE OR REPLACE TYPE employee_table_type AS TABLE OF employee_type;
/
create or replace PROCEDURE SAVE_EMPLOYEES(p_emp_insert_array in employee_table_type) AS
BEGIN
FORALL i IN p_emp_insert_array.first .. p_emp_insert_array.last
insert into employee(
empno,
FNAME,
LNAME,
EMAIL)
values (
empno_seq.nextval,
p_emp_insert_array(i).FNAME,
p_emp_insert_array(i).LNAME,

END SAVE_EMPLOYEES;

SqlStructArrayValue in spring has some issue with OracleConnection casting so i created my own one similar to them.
import java.sql.Connection;
import java.sql.SQLException;
import java.sql.Struct;
import oracle.jdbc.OracleConnection;
import org.springframework.dao.InvalidDataAccessApiUsageException;
import org.springframework.data.jdbc.support.oracle.SqlStructArrayValue;
import org.springframework.data.jdbc.support.oracle.StructMapper;
/**

public class OracleSqlStructArrayValue<T> extends SqlStructArrayValue<T> {
private T[] values;
/**
* The object that will do the mapping *
*/
private StructMapper<T> mapper;
/**
* The type name of the STRUCT *
*/
private String structTypeName;
/**
* The type name of the ARRAY *
*/
private String arrayTypeName;
public OracleSqlStructArrayValue(T[] values, StructMapper<T> mapper, String structTypeName) {
super(values, mapper, structTypeName);
this.values = values;
this.mapper = mapper;
this.structTypeName = structTypeName;
}
public OracleSqlStructArrayValue(T[] values, StructMapper<T> mapper, String structTypeName, String arrayTypeName) {
super(values, mapper, structTypeName, arrayTypeName);
this.values = values;
this.mapper = mapper;
this.structTypeName = structTypeName;
this.arrayTypeName = arrayTypeName;
}
#Override
protected Object createTypeValue(Connection conn, int sqlType, String typeName) throws SQLException {
if (typeName == null && arrayTypeName == null) {
throw new InvalidDataAccessApiUsageException(
"The typeName for the array is null in this context. Consider setting the arrayTypeName.");
}
Struct[] structValues = new Struct[values.length];
for (int i = 0; i < values.length; i++) {
structValues[i] = mapper.toStruct(values[i], conn, structTypeName);
}
OracleConnection oracleConn = (OracleConnection) conn;
return oracleConn.createOracleArray(typeName != null ? typeName : arrayTypeName, structValues);
}
}
Now in your DAO Class do the following...
public class EmployeeDAO {
private static final Logger logger = LoggerFactory.getLogger(EmployeeDAO.class);
#Autowired
private DataSource dataSource;
private JdbcTemplate jdbcTemplate;
private SimpleJdbcCall saveEmployeesArrayCall;
#PostConstruct
private void postConstruct() {
jdbcTemplate = new JdbcTemplate(dataSource);
this.saveEmployeesArrayCall =
new SimpleJdbcCall(dataSource).withProcedureName(SQLConstants.SAVE_EMPLOYEES_STORE_PROC)
.withoutProcedureColumnMetaDataAccess()
.declareParameters(new SqlParameter("p_emp_insert_array", Types.ARRAY, SQLConstants.EMPLOYEE_OBJ_TABLE_TYPE));
}
public void saveEmployees(List<Employee> employees) {
Map<String, Object> in = new HashMap<>();
in.put("p_emp_insert_array", new OracleSqlStructArrayValue<>(employees.toArray(new Employee[0]), new EmployeeStructMapper(), SQLConstants.EMPLOYEE_OBJ_TYPE));
saveEmployeesArrayCall.execute(in);
}
}
