pool13433015 mins

Sharing is caring!

Web Service แบบ RESTful protocol ได้รับความนิยมเป็นอย่างมากในปัจจุบัน หลายภาษามี web framework ของตัวอย่าง Java Spring Framework ก็เช่นกัน

SpringBoot เป็น Framework ที่ได้รับความนิยมมากกับ Java เพราะด้วยความง่ายที่เป็นสิ่งที่ถูกพัฒนาเพื่อแก้ปัญหาในการ Setup Project ที่ค่อนข้างยุ่งยากและซับซ้อนในการ Build RESTful API ขึ้นมาใช้งาน Springboot จึงได้รับความนิยมและได้เปรียบเรื่องความรวดเร็วในการ Setup Project

สิ่งที่จะได้รับเมื่ออ่านบทความบทนี้จบ

  • Create Springboot Project
  • CRUD Data with H2 Database
  • Use GET,POST,PUT,DELETE Methods
  • Content-Type : “application/json”
  • MockMvc
  • CrudRepository Interface crud



เริ่มกันเลย

  1. init project https://start.spring.io/
    1. 1
  2. เพิ่ม h2database ในไฟล์ pom.xml
