Question

我正在开发一个SpringMVC项目。我想在DispatcherServlet中创建xmlview bean。

的DispatcherServlet-context.xml中

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

    <import resource="classpath:config/spring/timeres-dbconfig-context.xml" />
    <import resource="classpath:config/spring/timeres-hibernate-config-context.xml" />
    <import resource="classpath:config/spring/timeres-txnconfig-context.xml" />

    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/" />
        <property name="suffix" value=".jsp" />
    </bean>

    <bean id="messageSource"
        class="org.springframework.context.support.ResourceBundleMessageSource">
        <property name="basename" value="messages" />
    </bean>
    <mvc:resources location="/resources/" mapping="/resource/**" />
    <bean id="multipartResolver"
        class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

        <!-- setting maximum upload size -->
        <property name="maxUploadSize" value="100000" />

    </bean>

    <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
    <property name="defaultViews">
        <list>
            <ref bean="jsonView" />
            <ref bean="xmlView" />
        </list>
    </property>
    </bean>
    <bean id="jsonView"
        class="org.springframework.web.servlet.view.json.MappingJacksonJsonView">
        <property name="prettyPrint" value="true" />
    </bean>
    <bean id="xmlView" class="org.springframework.web.servlet.view.xml.MarshallingView">
    <constructor-arg>
        <bean class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
            <property name="classesToBeBound">
                <list>
                    <value>com.packt.webstore.domain.Product</value>
                </list>
            </property>
        </bean>
    </constructor-arg>
    </bean>

</beans>

在我的Project.java domai类中，我添加了@XmlRootElement注释。但是我在控制台中出现了错误，如下所示，

SEVERE: Context initialization failed

我可以理解问题在于xmlview bean的创建。我该如何解决这个错误？

Answer 1

尝试将http://www.springframework.org/schema/oxm http://www.springframework.org/schema/oxm/spring-oxm-1.5.xsd"添加到xsi:schemaLocation。

并在依赖项中添加spring-core和spring-web。

并建议您使用相同版本的spring framework套餐。

    <properties>           
       <spring-version>3.2.9.RELEASE</spring-version>
    </properties>
    <!--  ... -->
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>${spring.version}</version>
    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>${spring.version}</version>
    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>${spring.version}</version>
    </dependency>
    <dependency>
       <groupId>org.springframework</groupId>
       <artifactId>spring-oxm</artifactId>
       <version>${spring-version}</version>
    </dependency>

Answer 2

尝试使用jax-b作为xml转换提供程序

<dependency>
    <groupId>com.sun.xml.bind</groupId>
    <artifactId>jaxb-impl</artifactId>
    <version>2.2.11</version>
</dependency>

Answer 3

您在申请中缺少spring-oxm依赖

 <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>4.1.6.RELEASE</version>
     </dependency>

创建名为'org.springframework.web.servlet.view.ContentNegotiatingViewResolver＃0'的bean时出错
