\nDialogflow is a natural language processing platform by Google, facilitating the creation of conversational interfaces. It interprets user input in various formats, allowing developers to build interactive applications, chatbots, and more.<\/p>\n
2. Setting Up a Dialogflow Agent Step 1: Agent<\/strong> Create a new Dialogflow agent. Call it whatever you want. My Agent\u2019s name is \u201cMovieBot\u201d.<\/p>\n Step 2: Intents<\/strong> NOTE :<\/strong> E.g.<\/strong> : If my intent is \u201cListOfMovies\u201d then it will check mis-spells for movies or list or something related to \u201cListOfMovies\u201d. It won\u2019t cover every mis- spells and to overcome that, Your back-end will help you by implementing additional logics.<\/p>\n b)<\/strong> There are two pre-defined Intents : These intents have their pre-defined phrases and responses which is very helpful and Dialogflow does it all on its own.<\/p>\n Step 3: Training Phrases<\/strong> When you update your Training Phrases in Dialogflow, and save it, the Agent will train itself, and after completion of Agent\u2019s training, at the bottom-right, it will notify by \u201cAgent training completed\u201d.<\/p>\n Step 4: Entities<\/strong> a)<\/strong> User says \u201cI want two movies\u201d. Now, you\u2019re defining no. of movies that you want so this \u201cNUMBER\u201d which is Two here will be treated as an entity.<\/p>\n But, Hey! Dialogflow here also gives you comfort i.e. you don\u2019t need to create an entity for this Number. It provides you that under System Entity : @ sys.number.<\/p>\n Similarly, there are various types of pre-defined entities that Dialogflow have(System entity, RegExp Entity etc).<\/p>\n b)<\/strong> User says \u201cI want action movies\u201d. Now, you\u2019re defining the genre of movie according to your choice so this \u201cGENRE\u201d which is Action here will be treated as a Custom Entity.<\/p>\n But this will not be under pre-defined entities thus, in this case, a Custom Entity will be needed. So, create Entity named \u201cGenreOfMovies under \u201cListOfMovies\u201d intent.<\/p>\n In this way, pre-defined entities and custom ones work but there\u2019s more that you can explore!!<\/p>\n Step 5: Fulfillments<\/strong> b)<\/strong> If an input matches any Intent and webhook is enabled for that Intent, Dialogflow is going to call that provided API with the WebhookRequest object as payload.<\/p>\n Step 6: Training Responses<\/strong> b)<\/strong> In case the webhook fails, the provided text in Responses section will be the fallback.<\/p>\n 3. Setting Up a Spring Boot Application Step 1: Create a Spring Boot Project<\/strong> Step 2: Add Dialogflow Dependencies Step 3: Configure Dialogflow Credentials<\/strong> Step 4: Create Controller, Service & Repository Classes Respectively<\/strong> Step 5: Add-ons in Project<\/strong> 4. Create Public URL for your Project<\/strong> NGROK<\/strong> : Ngrok is a tunneling service that exposes local servers to the internet, \u201cngrok.exe http 8082\u201d Eg : My server.port is 8082, use your port in place of Adding the public URL with your post-mapping endpoint will completely connect your application with Dialogflow (My end-point is \u201cgetMovieData\u201d). Then, Save it.<\/p>\n And with that, Integrating Dialogflow into a Spring Boot Application has been done !!<\/p>\n LET\u2019S CHECK WHETHER INTEGRATION IS SUCCESSFUL OR NOT<\/strong> – IMPORTANT<\/strong> – Fulfillment Response will be shown only if Dialogflow is connected to SpringBoot Application (backend).<\/p>\n Now in the FulfillmentText of Fulfillment Response\u2026<\/p>\n Training Response (\u201chere are some popular movie<\/strong>s\u201d) from Dialogflow and Response from Back-end (SpringBoot) \u201c: Pursuit of Happyness, OMG<\/strong>\u201d are concatenated together (in the code itself) and giving us our desired response using Dialogflow & SpringBoot Integration.<\/p>\n NOTE :<\/strong> IMPORTANT :<\/strong><\/p>\n The Fulfillment Status proves that Integration has been done successfully. Here\u2019s the Demo of Integrating Dialogflow into a SpringBoot Application :<\/p>\n In the ever-evolving landscape of software development, Google’s Dialogflow is a powerful tool that enables developers to build conversational interfaces form applications, and integrating it with a Spring Boot backend can provide a seamless and efficient user experience.

\n<\/strong>
\nBefore integrating Dialogflow into a Spring Boot application, you need to set up a Dialogflow agent. Follow these steps:<\/p>\n
\nAn agent is a virtual conversational assistant that processes user input, identifies intents and entities, and generates appropriate responses.<\/p>\n
\nIntents represent the user's intentions. Let\u2019s say, I want to create a MovieBot so in that case my intent could be \u201cListOfMovies\u201d or \u201cShow Ratings Of a Movie\u201d and so on.<\/p>\n
\na)<\/strong> You can enable Auto-Spell Check by exploring the Agent\u2019s Setting ->> ML Settings. However, this spell-check checks for mis-spells allied to a particular Intent only.<\/p>\n
\n1. Default Welcome Intent<\/strong> : If you say hi\/hello\/greetings etc, Dialogflow handles it internally and gives you default response.
\n2. Default Fallback Intent<\/strong> : If user says something which Dialogflow is unable to understand, it will return Fallback.<\/p>\n
\nDialogflow gives you the ease by adding Training Phrases. If you add \u201clist of movies\u201d as a training phrase then it will use its intelligence and answer questions such as \u201cCould you please give me the list of movies\u201d
\nOR
\n\u201cShow me the list of movies\u201d, you don\u2019t separately need to enter these phrases. That\u2019s the Intelligence of Dialogflow.<\/p>\n
\nEntities are used to extract important information from user input. Define these to train your agent to provide more accurate and context-aware responses.
\nEx : For Intent named \u201cListOfMovies\u201d,<\/p>\n
\na)<\/strong> Now, the most awesome part of Dialogflow! \u2018THE WEBHOOKS\u2019 In the Fulfillment section for every agent, Dialogflow lets us provide a webhook, which is basically just a REST API that expects a parameter of a valid WebhookRequest object (JSON Format).<\/p>\n
\na)<\/strong> Add some responses in the Responses section for the intent. Because if we enable webhook for an Intent, it\u2019s the webhook\u2019s responsibility to send back the response text, as the reply for the input.<\/p>\n
\n<\/strong>
\nNow that you have a Dialogflow agent set up, let's integrate it into a Spring Boot
\napplication.<\/p>\n
\nUse your preferred IDE or the Spring Initializer (https:\/\/start.spring.io\/) to create a new Spring Boot project with the necessary basic dependencies.<\/p>\n
\n<\/strong><\/p>\n<!--\r\nhttps:\/\/mvnrepository.com\/artifact\/com.google.apis\/google-api-services-dialogflow -->\r\n<dependency>\r\n<groupId>com.google.apis<\/groupId>\r\n<artifactId>google-api-services-dialogflow<\/artifactId>\r\n<version>v3-rev20231011-2.0.0<\/version>\r\ndependency>\r\n<!--\r\nhttps:\/\/mvnrepository.com\/artifact\/com.google.cloud\/google-cloud-dialogflow\r\n<dependency>\r\n<groupId>com.google.cloud<\/groupId>\r\n<artifactId>google-cloud-dialogflow<\/artifactId>\r\n<version>2.2.0<\/version>\r\n<\/dependency>\r\n--><\/pre>\n
\nCreate a Configuration file in your IDE provided with @ConfigurationProperties. To use this file, add dialogflow configurations in application.properties so that it can be used later (I\u2019m creating MovieBot therefore, names are in its accordance, you\u2019re free to use any).<\/p>\n# Dialogflow endpoint path \r\ndialogflow.endpoint-\/dialogflow-webhook\r\n#Dialogflow configurations\r\nmoviebotconfiguration.google.name=MovieBot\r\nmoviebotconfiguration.google.projectid= concurrency-yo9g\r\nmoviebotconfiguration.google.languageCode: en \r\npackage com.dialogflow.moviebot.config;\r\nimport org.springframework.boot.context.properties.ConfigurationProperties;\r\n@Configuration\r\n@EnableConfigurationProperties\r\n@Configuration Properties (prefix = \"moviebotconfiguration.google\")\r\npublic class MovieBotConfiguration {\r\nprivate String name; \r\nprivate String projectid; \r\nprivate String languageCode;<\/pre>\n
\nCreate Controller, Service and Repository classes respectively using given demo references and add needed logic implementations according to your requirements.<\/p>\n@RestController\r\npublic class MovieController {\r\nprivate static final Logger Logger = LoggerFactory.getLogger(MovieController.class);\r\n@Autowired\r\nprivate MovieBotConfiguration movieBotConfiguration;\r\n@Autowired\r\nprivate MovieService movieService;\r\n@PostMapping(\"\/getMovieData\")\r\npublic WebHookResponse handleWebHook (@RequestBody WebHookRequest webHookRequest) throws Exception {\r\nString projectId\r\nmovie BotConfiguration.getProjectid();\r\nString languageCode = movieBotConfiguration.getLanguageCode();\r\nmovieService.getFulfillmentTextRequest(webHookRequest);\r\nfinal String queryText = movieService.getQueryText(webHookRequest); String sessionId movieService.getSessionId (webHookRequest);\r\nString displayName=movieService.getDisplayName (webHookRequest);\r\n\/\/ CASE1: check the intent.displayName with \"listOfMovies\"\r\nif (\"ListOfMovies\".equals(displayName)) {\r\n}\r\nreturn movieService.handleListOfMovies Intent(queryText, sessionId); \r\n@Service\r\npublic class MovieService {\r\n@Autowired\r\nprivate MovieRepository movieRepo;\r\nWebHookResponse webHookResponse = new WebHookResponse();\r\nString fulfillmentTextRequest;\r\nString session;\r\npublic String getMovieData() {\r\nString movies = \"\";\r\nList<Movies> unfilteredMovies = movieRepo.findAll();\r\nfor (Movies movie : unfilteredMovies) {\r\nmovies movies\r\nmovie.getMovieName() +\r\nreturn movies;\r\n}\r\n}\r\npublic String getQueryText (WebHookRequest webHookRequest) { return webhookRequest.getQueryResult().getQueryText();\r\n}\r\n@Repository\r\npublic interface MovieRepository extends JpaRepository<Movies, Long>{\r\n}<\/pre>\n
\nThere are pre-defined classes for Intents, QueryText, QueryInputs etc. for developers use to connect dialogflow and SpringBoot however its upto you whether you want to use them or create your own user-defined models. I\u2019ve chosen the second one. You can choose any.<\/p>\n
\nThe SpringBoot application that you\u2019ve created must be local, right. But, Dialogflow needs Public Secured URL (HTTPS only) to connect with your application. I\u2019ve used NGROK to convert my Local URL to Public URL however it is valid for 2 hours only.<\/p>\n
\nproviding a public URL for testing and debugging web applications.
\n1. Download<\/strong> \u2192 Create your Account<\/strong> \u2192 Login<\/strong> \u2192 Go to Settings<\/strong> \u2192 Copy your Auth-Token<\/strong>
\n2. Open Command Prompt<\/strong> \u2192 Paste Auth-Token<\/strong> , then write the following :<\/p>\n
\n8082. And, this will give you Public URL using your Local URL.<\/p>\n![\"\"](\"https:\/\/innovationm.co\/wp-content\/uploads\/2024\/02\/Screenshot-2024-02-15-172516-300x116.png\")
<\/p>\n
\nAs you can see, in FulfillmentText (\u201chere are some popular movies\u201d) of Fulfillment Request, there are NO Movie Names i.e. it shows only Training Response from Dialogflow.<\/p>\n![\"Integrating](\"https:\/\/innovationm.co\/wp-content\/uploads\/2024\/02\/Screenshot-2024-02-15-172841-300x164.png\")
<\/p>\n
\na) I\u2019ve taken two movie names here for demo purpose only<\/strong> however it is not the best practice in Real-World Scenario Projects.
\nb) In the movie name mentioned above, It is Happyness in Pursuit Of Happyness, not Happiness.<\/p>\n![\"Training](\"https:\/\/innovationm.co\/wp-content\/uploads\/2024\/02\/Screenshot-2024-02-15-172942-300x90.png\")
