QUESTION

vue single file components naming; is it important?

Asked 2021-Jun-16 at 00:25

What's the point of the name of a single file vue component?

In this example:

<template>
  <div class="inventory-section">    
    <draggable v-model="itemSectionProps.itemSectionCategory">
      <transition-group>
        <div
          v-for="category in itemSectionProps.itemSectionCategory"
          :key="category.itemSectionCategoryId"
        >
          <!-- <p>{{ category.itemSectionCategoryName }}</p>  -->
          <inventory-section-group :itemSectionGroupProps="category">
          </inventory-section-group>
        </div>
      </transition-group>
    </draggable>
  </div>
</template>

<script>
import InventorySectionGroup from "./InventorySectionGroup";
import draggable from "vuedraggable";

export default {
  name: "Inventory",
  components: {
    InventorySectionGroup,
    draggable,
  },

inventory section group is named like:

<script>
import InventoryItem from "./InventorySectionGroupItemC";

export default {
  name: "Do I even have a point?",
  components: {
    InventoryItem,
  },
  props: {
    itemSectionGroupData: {
      type: Object,
    },
  },
};
</script>

so, does the name in the component matter?

After some testing, all components seem to work as long as they're translated from camel to kebap-case when imported (and used). Is this the case?

ANSWER

Answered 2021-Jun-16 at 00:25

A good justification for the name is that lets say you have a naming convention to your files and for components.

For example if all components are named with what they are but not appended with comp (ie: Inventory.vue instead of InventoryComp.vue) and when you use them you want to be more explicit about what they are (components) so you want to use this component like this: <inventory-comp />. An easy way to do this is to use the name property and set it like this in your Inventory.vue:

name: 'InventoryComp` // or inventory-comp

QUESTION

Create http and https endpoint using camel in the same server with jetty

Asked 2021-Jun-10 at 19:56

I am trying to create HTTP and HTTPS endpoint in one of my web service. I want secure few endpoints with HTTPS and other endpoints with plain HTTP.

I am using the below code to do the same.

    public void configure() {
        configureJetty();
        configureHttp4();
        //This works with configuring Jetty
        from("jetty:https://0.0.0.0:8085/sample1/?matchOnUriPrefix=true")
                .to("file://./?fileName=out.csv");
        //This url does not working with the configuring the jetty with configure jetty this works.
        from("jetty:http://0.0.0.0:8084/sample2/?matchOnUriPrefix=true")
                .to("file://./?fileName=out2.csv");
    }

private void configureJetty() {
        KeyStoreParameters ksp = new KeyStoreParameters();
        ksp.setResource("./trustStore.jks");
        ksp.setPassword("someSecretPassword");
        KeyManagersParameters kmp = new KeyManagersParameters();
        kmp.setKeyStore(ksp); kmp.setKeyPassword("someSecretPassword");
        SSLContextParameters scp = new SSLContextParameters();
        scp.setKeyManagers(kmp);
        JettyHttpComponent jettyComponent = getContext().getComponent("jetty", JettyHttpComponent.class);
        jettyComponent.setSslContextParameters(scp);
    }

The https works fine with this setup but the http endpoint does not work. If I remove the method call to configure Jetty the HTTP endpoint works. How I can configure both in the same server? I can not use spring boot but only plain camel components.

I have created a github repository with the sample code. You can find it here. sample code

ANSWER

Answered 2021-Jun-10 at 19:56

You can

create two distinct instances of jetty component, one for plain http, the other for https.
register each of them with a specific alias ("jetty" and "jettys")
use appropriate alias in your endpoint uris "from("jettys:...")

CDI Example:

@Produces
@ApplicationScoped 
@Named("jetty")
public final JettyHttpComponent createJettyComponent1() {       
    return this.configureJetty(false);
}

@Produces
@ApplicationScoped 
@Named("jettys")
public final JettyHttpComponent createJettyComponent2() {       
    return this.configureJetty(true);
}  

private void configureJetty(boolean ssl) {
   ...
    JettyHttpComponent jettyComponent = new JettyHttpComponent();
    if (ssl) {
        jettyComponent.setSslContextParameters(scp);
    }   
}

How To Run Kafka Camel Connectors On Amazon MSK

Asked 2021-Jun-10 at 09:35

Context: I followed this link on setting up AWS MSK and testing a producer and consumer and it is setup and working correctly. I am able to send and receive messages via 2 separate EC2 instances that both use the same Kafka cluster (My MSK cluster). Now, I would like to establish a data pipeline all the way from Eventhubs to AWS Firehose which follows the form:

Azure Eventhub -> Eventhub-to-Kafka Camel Connector -> AWS MSK -> Kafka-to-Kinesis-Firehose Camel Connector -> AWS Kinesis Firehose

I was able to successfully do this without the use of MSK (via regular old Kafka) but for unstated reasons need to use MSK now and I can't get it working.

Problem: When trying to start the connectors between AWS MSK and the two Camel connectors I am using, I get the following error:

These are the two connectors in question:

Goal: Get these connectors to work with the MSK, like they did without it, when they were working directly with Kafka.

Here is the issue for Firehose:

Task threw an uncaught and unrecoverable exception (org.apache.kafka.connect.runtime.WorkerTask:177)
com.amazonaws.services.kinesisfirehose.model.AmazonKinesisFirehoseException: The security token included in the request is invalid

MSK doesn't offer Kafka Connect as a service. You'll need to install this on your own computer, or on other AWS compute resources. From there, you need to install the Camel connector plugins

Mongodb Java SDK not using the @BsonProperty as the field name

Asked 2021-Jun-04 at 17:16

I am using the mongodb-driver-sync library, version: 4.2.3 in my Java project to insert values into a MongoDB collection. When I insert them, the field names are not the values in the @BsonProperty annotation but the lower camel case of the Java variable names. How do I make it use my annonation value?

My POJO is:

public class Product {
    private ObjectId id;
    @BsonProperty(value = "product_sk")
    private String ProductSK;
    @BsonProperty(value = "product_id")
    private String ProductID;
    @BsonProperty(value = "upc")
    public String UPC;

    public ObjectId getId() {
        return id;
    }

    public Product setId(ObjectId id) {
        this.id = id;
        return this;
    }

    public String getProductSK() {
        return ProductSK;
    }

    public Product setProductSK(String productSK) {
        ProductSK = productSK;
        return this;
    }

    public String getProductID() {
        return ProductID;
    }

    public Product setProductID(String productID) {
        ProductID = productID;
        return this;
    }

    public Product setUPC(String uPC) {
        UPC = uPC;
        return this;
    }
}

My insertion code is:

public void insertProduct(List<Product> products) {
    ConnectionString connectionString = new ConnectionString(MONGO_URI);
    CodecRegistry pojoCodecRegistry = fromProviders(PojoCodecProvider.builder().automatic(true).build());
    CodecRegistry codecRegistry = fromRegistries(MongoClientSettings.getDefaultCodecRegistry(), pojoCodecRegistry);
    MongoClientSettings clientSettings = MongoClientSettings.builder()
                                                            .applyConnectionString(connectionString)

The BSON entered is:

{ "_id" : ObjectId("60afb7be0af8954d7ce91b8f"), "productID" : "test1", "productSK" : 123, "uPC" : "test2" }

It should be:

{ "_id" : ObjectId("60afb7be0af8954d7ce91b8f"), "product_id" : "test1", "product_sk" : 123, "upc" : "test2" }

My dependencies are:

implementation 'com.google.code.gson:gson:2.8.6'
implementation group: 'org.mongodb', name: 'mongodb-driver-sync', version: '4.2.3'
implementation group: 'org.mongodb', name: 'mongodb-crypt', version: '1.2.0'

Maybe it is a matter of convention. Your properties all start with capital letters. Since getter/setter convention advise that this kind of property should start with low case letters I would try something like this:

private ObjectId id;
@BsonProperty(value = "product_sk")
private String productSK; // instead of ProductSK
@BsonProperty(value = "product_id")
private String productID; // instead of ProductID
@BsonProperty(value = "upc")
public String upc; // or uPC

AMQ Error reading in simpleString, length=xxx is greater than readableBytes=yyy

Asked 2021-Jun-03 at 17:19

I'm trying to work out how to fix this ActiveMQ Artemis error.

Seems the occasional message is too big for SimpleString, and isn't sending, and it goes to the DLQ.

java.lang.IndexOutOfBoundsException: Error reading in simpleString, length=1366648 is greater than readableBytes=127646@ClientLargeMessageImpl[messageID=578576793, durable=true, address=AuthCorrespondence.sendmail,userID=7f72137c-c3a3-11eb-87f7-0242c0a8e003,properties=TypedProperties[__AMQ_CID=b3f70eb1-be3c-11eb-87f7-0242c0a8e003,_AMQ_LARGE_SIZE=127651,_AMQ_ROUTING_TYPE=1]]

The most likely issue I can see is the similarity between readableBytes=127646 and _AMQ_LARGE_SIZE=127651.

From the docs, though, this _AMQ_LARGE_SIZE is the threshold for Large Messages, and it is supposed to be 2GB, and this message is what, 1.36MB?

What's going on?

I'm in Fuse/OSGi. 2.6.3.redhat-00015 for ActiveMQ Artemis JMS Client OSGi. 2.21.5 for camel-amqp. I can't work out what Artemis version it is. There's 1000+ successful deliveries. Just 6 fails.

ANSWER

Answered 2021-Jun-03 at 17:19

The 2.6.3.redhat-00015 version corresponds to AMQ 7.2.3 which is quite old at this point. The current AMQ release is 7.8.1. I strongly recommend you upgrade as it's likely you're hitting a bug that's already been fixed.

You may be able to work around the issue by increasing the minimum large message size (e.g using minLargeMessageSize on core client URLs or amqpMinLargeMessageSize on your AMQP acceptor). For what it's worth, the stack-trace indicates that the core JMS client (i.e. not AMQP) is in use when the exception is thrown.

Lastly, it's worth noting that the default minimum large message size is 100 KB not 2 GB as explained in the documentation.

QUESTION

Calculate length of 2 Strings and add them fails

Asked 2021-Jun-02 at 13:34

I am having a problem with a string length calculation which I can't solve. So the whole thing is from a book I am working through on kotlin programming: Big Nerd Ranch Guide. There is a tavern menu that should be formatted in code. There is a menu list provided which looks like this:

shandy,Dragon's Breath,5.91
elixir,shirley temple,4.12
meal,goblet of la croix,1.22
desert dessert,pickled camel hump,7.33
elixir,iced boilermaker,11.22

This list should be formatted into something like this:

*** Welcome to Taernyl's Folly ***

Dragon's Breath...............5.91
Shirley Temple................4.12
Goblet Of La Croix............1.22
Pickled Camel Hump............7.33
Iced Boilermaker.............11.22

So I have created a function that takes the menu data and splits it based on the comma (thanks for the correction @gidds). I don't need the first entry of each row. This is the function:

fun createMenuList(menuData: List<String>) {
    // print the Header with the Tavern Name
    println("*** Welcome to $TAVERN_NAME ***\n")

    // List of the parts of the beverage name since I need to capitalize each part of the name
    var nameList: List<String>

    menuData.forEachIndexed { _, menuData ->
        // the menu data is split by comma and and stored in beverageName and beveragePrice
        var (_, beverageName, beveragePrice) = menuData.split(",")

        // next line I calculate the dots I need to fill in the
        // space between the name and the price based on a line length of 34
        val dotCount = 34 - (beverageName.length + beveragePrice.length)

        // if I print the calculations for both Strings the calculation works
        // for the beverageName but not for beveragePrice, it's always 5 even though it is not
        println("Namelength:${beverageName.length} Pricelength:${beveragePrice.length}")

        var counter = 0
        var dots = ""

        // add as many dots as calculated by the string operation for the space
        while (counter <= dotCount) {
            dots += "."
            counter++
        }

        nameList = beverageName.split(' ')
        var cappedName = ""
        for (name in nameList) {
            cappedName += name.replaceFirstChar { it.uppercase() } + " "
        }
        cappedName = cappedName.substring(0 until cappedName.length - 1)
        println("$cappedName$dots$beveragePrice")

    }
}

If I run the code the length of the beveragePrice always gets calculated as 5, even though it should be 4 for the first 4 entries. This results in the wrong line length for the first 4 entries, I don't know what I am doing wrong. Here is the result I get with the printed string lengths. The funny thing is the same code works on a windows machine correctly. I appreciate every help I can get so thanks in advance.

*** Welcome to Taernyl's Folly ***

Namelength:15 Pricelength:5
Dragon's Breath...............5.91
Namelength:14 Pricelength:5
Shirley Temple................4.12
Namelength:18 Pricelength:5

Namelength:18 Pricelength:5
Pickled Camel Hump............7.33
Namelength:16 Pricelength:5

Thanks everyone contributing to the answer of my question as Tenfour04, Henry Twist and gidds in the comments. Tenfour04 gave the initial right answer. Line breaks are getting added to the elements in the list after split. I have seen it on windows now happen as well. So one should always use trim() with split() when you read strings from a file I guess. Solution is:

var (_, beverageName, beveragePrice) = menuData.trim().split(",")
