Mencipta bot telegram menggunakan Spring Boot Pt.3: Quiz Bot

<h3>Mengisi pangkalan data</h3>Di sini kami akan menulis soalan kami dengan analogi dengan skrip permulaan pangkalan data.

DELETE
FROM java_quiz;

INSERT INTO java_quiz (question, answer_correct, option1, option2, option3)
VALUES ('What is a correct syntax to output "Hello World" in Java?', 'System.out.println("Hello World!");',
        'print("Hello World!");', 'sout("Hello World!");', 'Systemout.print("Hello world!");'),
       ('What is the correct way to create an object called foo of Bar class?', 'Bar foo = new Bar();',
        'Foo bar = new Foo();', 'Bar foo() = new Foo();', 'Foo bar() = new Bar();'),
       ('Which operator can be used to compare two values?', '==', '=', '&', '==='),
       ('Which method can be used to return a string in upper case letters?', 'toUpperCase()', 'camelCase()',
        'upperCase()', 'formatUpper()'),
       ('Which method can be used to find the length of a string?', 'length()', 'getSize()', 'len()', 'getLength()'),
       ('Which data type is used to create a variable that should store text?', 'String', 'Text', 'Varchar', 'const'),
       ('How to insert a comment?', '// like this', '# like this', '<-- like this -->', '/ like this');

Yang tinggal hanyalah membetulkan permohonan.yaml:

bot:
  name: JavaQuiz
  token: 1234567:AAF0Wru1Z60p8vPtKihx3odbwSv9O0y_-MM
spring:
  datasource:
    url: jdbc:postgresql://ec2-54-75-199-252.eu-west-1.compute.amazonaws.com:5432/d5p9skg6nin3mh?user=bozuqwnhjhoubl&password=8a40050de8a0014c14df49aeaac5880f1ac633cc20c78a4cc3b32323231
    driver-class-name: org.postgresql.Driver
    initialization-mode: never
  jpa:
    database-platform: org.hibernate.dialect.PostgreSQLDialect
    show-sql: true
    hibernate:
      ddl-auto: update

URL pangkalan data adalah berbeza daripada yang disenaraikan dalam medan URI pada Heroku, jadi berikut ialah helaian curang pantas tentang cara membinanya:

jdbc:postgresql://{Host}:{Port}/{Database}?user={User}&password={Password}

Jika kita melakukan semuanya dengan betul, maka apabila kita menjalankan main kita tidak akan melihat stacktrace, malah sebaliknya:

Mari cuba berkomunikasi dengan bot kami: Mari berkenalan Mari bermain Minta bantuan Selesai! Kami menulis bot kuiz. Sekarang kami mempunyai tugas besar di hadapan kami - kami memerlukan:

• memahami kod yang ditulis hari ini;
• baca dokumentasi Spring Data;
• tambah pembalak;
• melakukan pemfaktoran semula;
• menggunakan corak reka bentuk;
• memungkinkan untuk meminta bantuan bukan sahaja dengan Negeri.TIADA;
• menambah fungsi baharu;
• papan pendahulu;
• hanya mengeluarkan soalan unik;
• kategori soalan.

Saya harap anda mendapati artikel berganda ini membantu. Jika ya, letakkan bintang dalam repositori saya , saya akan gembira! Jika anda mempunyai sebarang soalan, kami akan membincangkannya dalam ulasan. Dan akhirnya - gambarajah projek: KEMASKINI 12.10: Kod projek telah disiarkan pada git sebagaimana adanya tanpa perubahan
