RestConfig.java

package ru.expbrain.flib.config; 

import org.springframework.context.annotation.ComponentScan; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.web.servlet.config.annotation.EnableWebMvc; 
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; 

@Configuration 
@EnableWebMvc 
@ComponentScan(basePackages = {"ru.expbrain.flib.rest.controller"}) 
public class RestConfig extends WebMvcConfigurerAdapter { 

}

BookController.java

package ru.expbrain.flib.rest.controller; 

import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestMethod; 
import org.springframework.web.bind.annotation.RequestParam; 
import org.springframework.web.bind.annotation.ResponseBody; 
import ru.expbrain.flib.rest.entity.Book; 

import java.util.concurrent.atomic.AtomicLong; 

@Controller 
public class BookController { 

    private final AtomicLong counter = new AtomicLong(); 

    @RequestMapping(value="/book", method = RequestMethod.GET) 
    public @ResponseBody Book greeting(@RequestParam(value="content", required=false, defaultValue="World") String name) { 
     return new Book(counter.incrementAndGet(), name); 
    } 
}

尽量克服路径的内容，顺便说一句根上下文路径去/

http://localhost:9080/rest/book

检查应用程序启动时的日志，您应该看到调度器映射的详细信息 – 2013-09-21 08:05:05

您确定您的'BookController'正在实例化吗？（您可以使用'@ PostConstruct'方法编写日志消息。） – chrylis

没有提到任何映射过程，但它显示mvc-dispatcher-servlet初始化 – ArchCC

谢谢Sotirios Delimanolis进行测试。

这是高速缓存的一些问题......无法解释发生了什么，因为它不是用清洁修复......但重新创建项目帮助和一切似乎都很好。
