Nie znaleziono klasy przy użyciu javaConfig

Question

Używam adnotacji do dynamicznego tworzenia fasoli, otrzymuję następujące błędy.

package demoproject; 

import org.springframework.context.annotation.Bean; 
import org.springframework.context.annotation.Configuration; 
@Configuration 
public class ProductFactory { 

    public ProductFactory() { 
     // TODO Auto-generated constructor stub 
    } 

    @Bean 
    public Product josh(){ 
     Product josh = new Battery(); 
     josh.setId("cdrw"); 
     josh.setPrice(100); 
     return josh; 
    } 
} 

web.xml

<!-- Bean for JavaConfig --> 
    <bean class='demoproject.ProductFactory' /> 
    <!-- be sure to include the JavaConfig bean post-processor --> 
    <bean class="org.springframework.config.java.process.ConfigurationPostProcessor"/>

Skąd mogę wiedzieć, co jest przyczyną błędu, a jest jakaś poprawka mogę spróbować tego?

Answer 1

Nie masz spring-core w swojej ścieżce klas środowiska wykonawczego. Musisz go dodać za pomocą odpowiedniej techniki do układu projektu, na przykład dodając go do Maven POM, jak sugeruje Simon.

Answer 2

od wiosny na 3.0, nie trzeba org.springframework.config.java.process.ConfigurationPostProcessor więcej, po prostu zdefiniować klasę Java-config jako fasoli w XML-config.

<bean class="demoproject.ProductFactory" /> 

spróbować usunąć

<bean class="org.springframework.config.java.process.ConfigurationPostProcessor"/>
