Groovy Spring Boot：如何执行 JSON POST、PUT、DELETE？答案

【问题标题】：Groovy Spring Boot: how to do JSON POST, PUT, DELETE?Groovy Spring Boot：如何执行 JSON POST、PUT、DELETE？

【问题描述】：

此示例适用于 URL 编码的 GET！我尝试使用不起作用的 JSON POST 来增强它。有人可以帮助我使用 JSON POST、DELETE 和 JSON PUT 以及 cmets 中的一些随附 curl 命令来演示这些命令吗？

/*
 * Begin commands to execute this file using Groovy with bash
 * spring run app.groovy &
 * sleep 10
 * curl -i -H "Accept: application/json" http://localhost:8080/greeting?name=siegfried -X GET
 * End commands to execute this file using Groovy with bash
 *
 *
 * $Log$

    }
    private static final String template = "Hello, %s!";
    private final AtomicLong counter = new AtomicLong();

    @RequestMapping("/greeting")
    public Greeting greeting(@RequestParam(value="name", defaultValue="World") String name) {
        return new Greeting(counter.incrementAndGet(), String.format(template, name));
    }

    // {"id":1,"content":"Hello, siegfried!"}

    //@RequestMapping(value="/g2", method=RequestMethod.GET) public Greeting greeting(@RequestParam(value="name", defaultValue="World") String name) { return new Greeting(counter.incrementAndGet(), String.format("Hello2, %s!", name));    }
    //@RequestMapping(value="/g3", method=RequestMethod.POST, headers = "Content-Type=application/json") public Greeting greeting(@RequestBody Greeting g) { return new Greeting(counter.incrementAndGet(), String.format("Hello2, %s!", g.content));    }

}

【问题讨论】：

您是否尝试过使用@Post（以及您的@RequestMapping 注释）来注释您的方法？

public class ContactRestController {

@RequestMapping(method=RequestMethod.GET)
  public List<Contact> getAll() {
    return new ArrayList<Contact>();
  }

  @RequestMapping(method=RequestMethod.POST)
  public Contact create(@RequestBody Contact contact) {
    return null;
  }

  @RequestMapping(method=RequestMethod.DELETE, value="{id}")
  public void delete(@PathVariable String id) {

  }

  @RequestMapping(method=RequestMethod.PUT, value="{id}")
  public Contact update(@PathVariable String id, @RequestBody Contact contact) {
  return null;
  }

}
