【问题描述】:
我目前正在学习有关 REST 的 Spring 教程(整个教程位于 spring.io/guides/tutorials/rest/)。我很确定我已经准确地遵循了指南。我有以下 EmployeeController 代码:
package com.example.buildingrest;
import java.util.List;
import org.springframework.web.bind.annotation.DeleteMapping;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.PutMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;
@RestController
class EmployeeController {
private final EmployeeRepository repository;
EmployeeController(EmployeeRepository repository) {
this.repository = repository;
}
// Aggregate root
@GetMapping("/employees")
List<Employee> all() {
return repository.findAll();
}
@PostMapping("/employees")
Employee newEmployee(@RequestBody Employee newEmployee) {
return repository.save(newEmployee);
}
// Single item
@GetMapping("/employees/{id}")
Employee one(@PathVariable Long id) {
return repository.findById(id)
.orElseThrow(() -> new EmployeeNotFoundException(id));
}
@PutMapping("/employees/{id}")
Employee replaceEmployee(@RequestBody Employee newEmployee, @PathVariable Long id) {
return repository.findById(id)
.map(employee -> {
employee.setName(newEmployee.getName());
employee.setRole(newEmployee.getRole());
return repository.save(employee);
})
.orElseGet(() -> {
newEmployee.setId(id);
return repository.save(newEmployee);
});
}
@DeleteMapping("/employees/{id}")
void deleteEmployee(@PathVariable Long id) {
repository.deleteById(id);
}
}
当我执行 CURL 命令以获取所有员工时,我成功了,当我执行 CURL 命令以通过 id 获取一名员工时,我成功了。问题是当我尝试发布新员工时。我正在使用来自教程的以下命令:
curl -X POST localhost:8080/employees -H 'Content-type:application/json' -d '{"name": "Samwise Gamgee", "role": "gardener"}'
我收到以下错误:
{"timestamp":"2020-03-20T13:28:56.244+0000","status":415,"error":"Unsupported Media Type","message":"Content type 'application/x-www-form-urlencoded;charset=UTF-8' not
supported","path":"/employees"}curl: (6) Could not resolve host: Samwise Gamgee,
curl: (6) Could not resolve host: role
curl: (3) [globbing] unmatched close brace/bracket in column 9
至于不匹配的右大括号/大括号,我上下查看了代码和CURL命令,找不到。至于不支持的媒体类型,我不明白为什么当我为整个应用程序使用 JSON 时它会声明 x-www-form-urlencoded。而且我直接从教程中复制了 curl 命令。
有什么想法吗?
【问题讨论】:
-
-H 'Content-Type:application/json'
-
这并没有解决问题
-
你在用windows吗?
-
我使用的是 Windows,但我在 Spring Tool Suite 的终端中使用 Bash shell。
