my rest controller

    package controllers;

    import org.springframework.beans.factory.annotation.Autowired;
    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.RequestBody;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;

    import model.Book;
    import service.IBookService;

    @RestController
    @RequestMapping("/books")
    public class BookRestController {
        @Autowired
        IBookService service;

        @PostMapping(path="/add")
        public void add(@RequestBody Book b) {
            service.add(b);
        }

        @GetMapping(path="/{id}")
        public Book searchById(@PathVariable("id") int id) {
            return service.recherche(id);
        }
    }

i use spring framework.

You are hitting a URL that doesn't have any mapping in your controller. Please share the controller code. — Minar Mahmud
I think you are attempting to call searchById. In that case hit this URL /books/1 — Minar Mahmud
i solve the problem .i had scan the wrong controller package. — taha
Great! Please add an answer and mark that as accepted! Happy coding! — Minar Mahmud

old springmvc-servlet.xml

    </bean>
<tx:annotation-driven />
<context:component-scan
    base-package="src/main/java/dao" />
<context:component-scan
    base-package="src/main/java/service" />
<context:component-scan
    base-package="src/main/java/controllers" />
<bean id="transactionManager"
    class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory"
        ref="entityManagerFactory" />
</bean>

the new file

    </bean>
<tx:annotation-driven />
<context:component-scan
    base-package="dao" />
<context:component-scan
    base-package="service" />
<context:component-scan
    base-package="controllers" />
<bean id="transactionManager"
    class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory"
        ref="entityManagerFactory" />
</bean>
