问题描述
我开始学习Spring Boot.我正在努力寻找带有多个RestControllers的示例，这向我表明我可能做错了事.我正在尝试一个非常简单的示例:目标是进行如下调用:
I am starting to learn Spring Boot. I am struggling to find an example with multiple RestControllers, which indicates to me that I may be doing something wrong. I am trying a very simple example: The goal is to make calls like the following:
localhost:8080/
localhost:8080/employees/bob
localhost:8080/departments
我只能显示localhost:8080/.其他调用返回响应:此应用程序没有针对/error的显式映射，因此您将其视为后备.
I can only get localhost:8080/ to display. The other calls return response: This application has no explicit mapping for /error, so you are seeing this as a fallback.
com.demo.departments
Department.java
DepartmentController.java
com.demo.employees
Employee.java
EmployeeController.java
com.demo
BootDemoApplication.java
代码:
package com.demo.departments
@RestController
@RequestMapping("/departments")
public class DepartmentController {
@RequestMapping("")
public String get(){
return "test..";
}
@RequestMapping("/list")
public List<Department> getDepartments(){
return null;
}
}
--------------------------------------------------------------------
package com.demo.employees
@RestController
@RequestMapping("/employees")
public class EmployeeController {
Employee e =new Employee();
@RequestMapping(value = "/{name}", method = RequestMethod.GET, produces = "application/json")
public Employee getEmployeeInJSON(@PathVariable String name) {
e.setName(name);
e.setEmail("[email protected]");
return e;
}
}
-----------------------------------------------------------------------
package com.demo
@RestController
@SpringBootApplication
public class BootDemoApplication {
public static void main(String[] args) {
SpringApplication.run(BootDemoApplication.class, args);
}
@RequestMapping("/")
String home(){
return "<html> This is the home page for Boot Demo.</html>";
}
推荐答案
显然，主类中的@springbootApplication表示法看不到不同程序包中的控制器.此处说明的解决方案 https://kamwo.me/java-spring -boot-mvc-ontroller-未调用/.
Apparently Controllers in different packages can't be seen with @springbootApplication notation in the main class. The solution explained here, https://kamwo.me/java-spring-boot-mvc-ontroller-not-called/.
