Can't inject Beans in Spring using annotations and xml

 原文  2013-06-10 08:31:08  7   3    java/ spring/ javabeans

Question

I'm having troubles using xml and annotations in the same project. Whenever I try to access a bean declared in xml, I get an exception. Here is my web.xml file : 

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    id="dynamease" version="3.0">
    <context-param>
        <param-name>contextClass</param-name>
        <param-value>
            org.springframework.web.context.support.AnnotationConfigWebApplicationContext
        </param-value>
    </context-param>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>com.dynamease.services</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>RESTServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextClass</param-name>
            <param-value>
                org.springframework.web.context.support.AnnotationConfigWebApplicationContext
            </param-value>
        </init-param>

        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>com.dynamease.web</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>RESTServlet</servlet-name>
        <url-pattern>/api/*</url-pattern>
    </servlet-mapping>
</web-app>

And here is the applicationContext.xml file located in the package com.dynamease.web : 

  <beans 
    xmlns:context="http://www.springframework.org/schema/context/spring-context.xsd">

    <context:component-scan base-package="com.dynamease.web.**" />
    <context:annotation-config />
    <!-- LDAP Beans -->
    <bean id="contextSource" class="org.springframework.ldap.core.support.LdapContextSource">
        <property name="url" value="ldap://192.168.1.10:10389" />
        <property name="base" value="dc=dynamease,dc=net" />
        <property name="userDn" value="uid=admin,ou=system" />
        <property name="password" value="secret" />
    </bean>

    <bean id="ldapTemplate" class="org.springframework.ldap.core.LdapTemplate">
        <constructor-arg ref="contextSource" />
    </bean>

    <bean id="personDao" class="com.example.dao.PersonDaoImpl">
        <property name="ldapTemplate" ref="ldapTemplate" />
    </bean>
</beans>

If I declare this : 

@Autowired
private LdapTemplate ldapTemplate;

I get this : 

ERROR [main] (FrameworkServlet.java:467) - Context initialization failed

I'm new to Spring, so I guess the trouble is in the configuration but I can't see where.

You are trying to use AnnotationConfigWebApplicationContext which is intended to be used with @Configuration and not xml based config files. Try switching to XmlWebApplicationContext instead and set 

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
</context-param>

If you are using Java-based configuration annotated with @Configuration then you can use @ImportResource to import your xml config.

UPD: Set your web.xml to 

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
  version="3.0">

<!-- The definition of the Root Spring Container shared by all Servlets and Filters -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>

<!-- Creates the Spring Container shared by all Servlets and Filters -->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- Processes application requests -->
<servlet>
    <servlet-name>RESTServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
    <async-supported>true</async-supported>
</servlet>

<servlet-mapping>
    <servlet-name>RESTServlet</servlet-name>
    <url-pattern>/api/*</url-pattern>
</servlet-mapping>

</web-app>

See example web.xml here on GitHub - SpringSource / spring-mvc-showcase

You need to specify your using annotation configuration and component scan for the beans. 

<context:component-scan base-package="package.with.beans.**" />
<context:annotation-config/>

Where package.with.beans.** is the package that contains the bean you are trying to inject the LdapTemplate . You can only inject beans into other beans, since they must be managed by the dependency injection container. So the class your trying to perform the injection in must be a bean and if that bean is established using an annotation, you must tell Spring to component scan to find that bean.

For example: 

package xx.yy.beans;

//Used to annotate beans
@Component
public class Foo{

@Autowired
private LdapTemplate ldapTemplate;

}

Then after importing the context namespace for your Spring configuration would contain: 

<beans>
    <context:component-scan base-package="xx.yy.beans.**" />
    <context:annotation-config/>

    <!-- LDAP Beans -->
    <bean id="contextSource" class="org.springframework.ldap.core.support.LdapContextSource">
        <property name="url" value="ldap:***" />
        <property name="base" value="dc=***,dc=***" />
        <property name="userDn" value="uid=***,ou=***" />
        <property name="password" value="***" />
    </bean>

    <bean id="ldapTemplate" class="org.springframework.ldap.core.LdapTemplate">
        <constructor-arg ref="contextSource" />
    </bean>

    <bean id="personDao" class="com.example.dao.PersonDaoImpl">
        <property name="ldapTemplate" ref="ldapTemplate" />
    </bean>
</beans>

您是否将@Component放在LdapTemplate类上？
