The first part of these courses<\/a> was all about setting up an build and deploy pipeline so that we could automate building a helm chart and deploying to our cloud hosted environment at Okteto.<\/p>\n\n\n\n

In this course we’re going to start adding more functionality so that we can demonstrate best practices around testing, logging, messaging and tracing.<\/p>\n\n\n\n

Updates<\/h2>\n\n\n\n

At this point, you may need to make some upates in order to get mongodb working with springboot. It appears that you need java sdk 13.0.2 (at least) in order to get spring boot to communicate with mongodb<\/a>. You’ll also need to update your intellij and dockerfile as well. Here’s the new dockerfile configuration<\/p>\n\n\n\n

# syntax=docker\/dockerfile:experimental\nFROM openjdk:15.0.2-slim-buster<\/span> as build\n\nCOPY .mvn .mvn\nCOPY mvnw .\nCOPY pom.xml .\n\n# download dependencies\nRUN .\/mvnw dependency:go-offline<\/span>\n\nCOPY src src\n\n# Setup the maven cache\nRUN --mount=type=cache,target=\/root\/.m2,rw .\/mvnw -B package -DskipTests\n\nFROM openjdk:15.0.2-slim-buster<\/span>\nCOPY --from=build target\/*.jar app.jar\nENTRYPOINT [\"java\", \"-jar\", \"app.jar\"]\n<\/code><\/pre>\n\n\n\n
I updated all the way up to 15.0.2, but I only use java 11 features so the maven pom doesn’t need to be updated.<\/p>\n\n\n\n
You can see that I also added a layer to retrieve dependencies in offline mode.  I am not sure this helps because the cache should already do this, but doesn’t hurt.<\/p>\n\n\n\n
Additionally, I didn’t like the image name as cloud_application <\/code>instead of cloud-application<\/code>.  So I updated the github workflows to use my new name.  If you make this change, you’ll need to update your helm values.yaml to pull the correct image down (and create the repo in canister.io with the preferred name)<\/p>\n\n\n\n
main.yml<\/p>\n\n\n\n

Create a Datastore<\/h2>\n\n\n\n
We’re going to setup a free mongodb cloud instance.  Go to the mongodb site<\/a> and create an account.  As you verify and create your account, make sure that you select Shared cloud database.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Choose AWS, use-east-1 and the rest of the defaults.  I change the cluster name to bullyrooks<\/code>.<\/p>\n\n\n\n
For Security, use username and password.  Choose a username and password and click Create User<\/code><\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
For connection, leave My Local Environment<\/code> and click Add My Current IP Address<\/code>.  Also, add 0.0.0.0\/0 (should allow all access), which will be needed for okteto to connect.  Then hit Finish and Close.  You’ll have to wait for the cluster to be created.  If you click on Connect<\/code>, choose Connect your Application<\/code>, then change Driver <\/code>to Java <\/code>and Version <\/code>to 4.3 or later<\/code>, you’ll see the connection string that you’ll need to connect to this instance.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Create the Repository Code<\/h2>\n\n\n\n
Checkout a new branch from main<\/code><\/p>\n\n\n\n
git checkout -b database<\/code><\/pre>\n\n\n\n
Add the mongodb database starter to your pom.xml in the dependencies section<\/p>\n\n\n\n
        <dependency>\n            <groupId>org.springframework.boot<\/groupId>\n            <artifactId>spring-boot-starter-data-mongodb<\/artifactId>\n        <\/dependency><\/code><\/pre>\n\n\n\n
Create these new packages under com.bullyrooks.cloud_application <\/p>\n\n\n\n
com.bullyrooks.cloud_application.repository\ncom.bullyrooks.cloud_application.repository.document\ncom.bullyrooks.cloud_application.repository.mapper<\/code><\/pre>\n\n\n\n
Create a new class under document <\/code>called MessageDocument<\/code>.  Add this content<\/p>\n\n\n\n
package com.bullyrooks.cloud_application.repository.document;\n\nimport lombok.Data;\nimport org.springframework.data.annotation.Id;\nimport org.springframework.data.mongodb.core.mapping.Document;\n\n@Document(\"messages\")\n@Data\npublic class MessageDocument {\n    @Id\n    private String messageId;\n    private String firstName;\n    private String lastName;\n    private String message;\n}<\/code><\/pre>\n\n\n\n
Now create an interface called MessageRepository <\/code>under com.bu<\/code>llyrooks.cloud_application.repository.  Add this content<\/p>\n\n\n\n
package com.bullyrooks.cloud_application.repository;\n\nimport com.bullyrooks.cloud_application.repository.document.MessageDocument;\nimport org.springframework.data.mongodb.repository.MongoRepository;\nimport org.springframework.stereotype.Repository;\n\n@Repository\npublic interface MessageRepository extends MongoRepository<MessageDocument, String> {\n\n}\n<\/code><\/pre>\n\n\n\n
Create the Controller Code<\/h2>\n\n\n\n
We’re going to be using mapstruct again to help create the mappers needed to support a ports and adapters design.  Add this to your pom.xml
\/code<\/p>\n\n\n\n
    <properties>\n        <java.version>11<\/java.version>\n        <org.mapstruct.version>1.4.1.Final<\/org.mapstruct.version>\n    <\/properties>\n\n...\n\n<!-- mapstruct -->\n<dependency>\n    <groupId>org.mapstruct<\/groupId>\n    <artifactId>mapstruct<\/artifactId>\n    <version>${org.mapstruct.version}<\/version>\n<\/dependency>\n<dependency>\n    <groupId>org.mapstruct<\/groupId>\n    <artifactId>mapstruct-processor<\/artifactId>\n    <version>${org.mapstruct.version}<\/version>\n<\/dependency><\/pre>\n\n\n\n
Create a dto <\/code>package in the controller <\/code>package and put two classes in there.<\/p>\n\n\n\n
package com.bullyrooks.cloud_application.controller.dto;\n\nimport lombok.Data;\n\n@Data\npublic class CreateMessageRequestDTO {\n    private String firstName;\n    private String lastName;\n    private String message;\n}\n<\/code><\/pre>\n\n\n\n
package com.bullyrooks.cloud_application.controller.dto;\n\nimport lombok.Data;\n\n@Data\npublic class CreateMessageResponseDTO {\n    private String firstName;\n    private String lastName;\n    private String message;\n}\n<\/code><\/pre>\n\n\n\n
Create a package called mapper <\/code>under controller <\/code>and put these two classes there<\/p>\n\n\n\n
package com.bullyrooks.cloud_application.controller.mapper;\n\nimport com.bullyrooks.cloud_application.controller.dto.CreateMessageRequestDTO;\nimport com.bullyrooks.cloud_application.service.model.Message;\nimport org.mapstruct.Mapper;\nimport org.mapstruct.factory.Mappers;\n\n@Mapper\npublic interface CreateMessageRequestDTOMapper {\n    CreateMessageRequestDTOMapper INSTANCE = Mappers.getMapper(CreateMessageRequestDTOMapper.class);\n\n    Message dtoToModel(CreateMessageRequestDTO userAccountEntity);\n\n}\n<\/code><\/pre>\n\n\n\n
package com.bullyrooks.cloud_application.controller.mapper;\n\nimport com.bullyrooks.cloud_application.controller.dto.CreateMessageRequestDTO;\nimport com.bullyrooks.cloud_application.controller.dto.CreateMessageResponseDTO;\nimport com.bullyrooks.cloud_application.service.model.Message;\nimport org.mapstruct.Mapper;\nimport org.mapstruct.factory.Mappers;\n\n@Mapper\npublic interface CreateMessageResponseDTOMapper {\n    CreateMessageResponseDTOMapper INSTANCE = Mappers.getMapper(CreateMessageResponseDTOMapper.class);\n\n    CreateMessageResponseDTO modelToDTO(Message message);\n\n}\n<\/code><\/pre>\n\n\n\n
Create a new class under controller and put this code there<\/p>\n\n\n\n
package com.bullyrooks.cloud_application.controller;\n\nimport com.bullyrooks.cloud_application.controller.dto.CreateMessageRequestDTO;\nimport com.bullyrooks.cloud_application.controller.dto.CreateMessageResponseDTO;\nimport com.bullyrooks.cloud_application.controller.dto.HelloWorldResponse;\nimport com.bullyrooks.cloud_application.controller.mapper.CreateMessageRequestDTOMapper;\nimport com.bullyrooks.cloud_application.controller.mapper.CreateMessageResponseDTOMapper;\nimport com.bullyrooks.cloud_application.service.MessageService;\nimport com.bullyrooks.cloud_application.service.model.Message;\nimport lombok.extern.slf4j.Slf4j;\nimport org.springframework.beans.factory.annotation.Autowired;\nimport org.springframework.web.bind.annotation.PostMapping;\nimport org.springframework.web.bind.annotation.RequestBody;\nimport org.springframework.web.bind.annotation.RestController;\n\n@RestController\n@Slf4j\npublic class MessageController {\n\n    @Autowired\n    MessageService messageService;\n\n    @PostMapping(\"\/message\")\n    public CreateMessageResponseDTO createMessage(@RequestBody CreateMessageRequestDTO request){\n        log.info(\"createMessage : {}\", request);\n        Message message = CreateMessageRequestDTOMapper.INSTANCE.dtoToModel(request);\n        Message response = messageService.saveMessage(message);\n        return CreateMessageResponseDTOMapper.INSTANCE.modelToDTO(response);\n    }\n\n}\n<\/code><\/pre>\n\n\n\n
What we’re doing here is defining a request and response data transformation object (dto) and mapping the dto into our internal representation to align with ports and adapters design.<\/p>\n\n\n\n
Create the Service Code<\/h2>\n\n\n\n
Make this package:<\/p>\n\n\n\n
com.bullyrooks.cloud_application.service.model\n<\/code><\/pre>\n\n\n\n
In the model package create this class<\/p>\n\n\n\n
package com.bullyrooks.cloud_application.service.model;\n\nimport lombok.Data;\n\n@Data\npublic class Message {\n    private String messageId;\n    private String firstName;\n    private String lastName;\n    private String message;\n}\n<\/code><\/pre>\n\n\n\n
Create this class in the service package<\/p>\n\n\n\n
package com.bullyrooks.cloud_application.service;\n\nimport com.bullyrooks.cloud_application.repository.MessageRepository;\nimport com.bullyrooks.cloud_application.repository.document.MessageDocument;\nimport com.bullyrooks.cloud_application.repository.mapper.MessageDocumentMapper;\nimport com.bullyrooks.cloud_application.service.model.Message;\nimport lombok.extern.slf4j.Slf4j;\nimport org.springframework.beans.factory.annotation.Autowired;\nimport org.springframework.stereotype.Service;\n\n@Service\n@Slf4j\npublic class MessageService {\n\n    @Autowired\n    MessageRepository messageRepository;\n\n    public Message saveMessage(Message message){\n        MessageDocument msgDoc = MessageDocumentMapper.INSTANCE.modelToDocument(message);\n        log.info(\"saving document: {}\", msgDoc);\n        MessageDocument returnDoc = messageRepository.save(msgDoc);\n        return MessageDocumentMapper.INSTANCE.documentToModel(returnDoc);\n    }\n}\n\n<\/code><\/pre>\n\n\n\n
Here we’re creating our actual service logic, but we’ll need to also create our mappers to the documents<\/p>\n\n\n\n
Create this class in a package called com.bullyrooks.cloud_application.repository.mapper<\/code><\/p>\n\n\n\n
package com.bullyrooks.cloud_application.repository.mapper;\n\nimport com.bullyrooks.cloud_application.repository.document.MessageDocument;\nimport com.bullyrooks.cloud_application.service.model.Message;\nimport org.mapstruct.Mapper;\nimport org.mapstruct.factory.Mappers;\n\n@Mapper\npublic interface MessageDocumentMapper {\n    MessageDocumentMapper INSTANCE = Mappers.getMapper(MessageDocumentMapper.class);\n\n    MessageDocument modelToDocument(Message model);\n\n    Message documentToModel(MessageDocument returnDoc);\n}\n\n<\/code><\/pre>\n\n\n\n
Set Configuration<\/h2>\n\n\n\n
Create an application.yml<\/code> file and add this code (or whatever matches your database configuration)<\/p>\n\n\n\n
spring:\n  application:\n    name: cloud_application\n  data:\n    mongodb:\n      uri: mongodb+srv:\/\/bullyrooks:${mongodb.password}@bullyrooks.4zqpz.mongodb.net\/bullyrooks?retryWrites=true&w=majority\n<\/code><\/pre>\n\n\n\n
And update your application run configuration in Intellij to insert your password.<\/p>\n\n\n\n
you will also need -Djdk.tls.client.protocols=TLSv1.2<\/code> to connect to mongodb<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Start up your application.  You should see it start and connect to mongodb<\/p>\n\n\n\n
