我在spring mvc得到了这个错误：org.springframework.beans.factory.BeanCreationException

时间：2015-07-22 09:08:11

标签： spring mongodb spring-mvc java-ee spring-data

我是春天的新人mvc＆amp; mongodb。我试图运行一个例子，但它抛出了一个bug。

错误是：

function addHyperlink(val,row){
    var temp = row.id;
    var temp2 = row.assignee;
    var temp3 = row.status;
    var temp4 = row.area;
    var temp5 = row.product;
    var temp1 = '<?php echo $_SESSION['username']; ?>';

    var redirect="edit_comments.php?id=" + temp + "&username=" + temp1 + "&assig=" + temp2 + "&stat=" + temp3 + "&areaa=" + temp4 + "&prod=" + temp5;


    return '<a href="#" onclick="window.open(\'' + redirect + '\', \'\', \'width=200, height=100\')">Edit Remarks</a>';

}

`

这是我的示例代码：

的pom.xml：

HTTP Status 500 - Servlet.init() for servlet dispatcher threw exception

type Exception report

message Servlet.init() for servlet dispatcher threw exception

description The server encountered an internal error that prevented it from fulfilling this request.

按照教程，请参阅以下代码：

<beans xmlns="http://www.springframework.org/schema/beans"     
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans  
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/context 
http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/mvc 
http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

    <bean id="viewResolver"
          class="org.springframework.web.servlet.view.InternalResourceViewResolver"
          p:prefix="/WEB-INF/views/"
          p:suffix=".jsp" />

    <context:component-scan base-package="com.breathejava" />
    <context:annotation-config />
    <mvc:annotation-driven />

    <bean id="mongoClient" class="org.springframework.data.mongodb.core.MongoFactoryBean">
        <property name="host" value="localhost" />
    </bean>

    <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
        <constructor-arg name="mongo" ref="mongoClient" />
        <constructor-arg name="databaseName" value="mydb" />
    </bean>

     <bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" />
</beans>

有趣的部分在这里：

<bean id="mongoClient" class="org.springframework.data.mongodb.core.MongoFactoryBean">
    <property name="host" value="localhost" />
</bean>

<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
    <constructor-arg name="mongo" ref="mongoClient" />
    <constructor-arg name="databaseName" value="mydb" />
</bean>

这是mongo客户端bean的创建。在你的代码中，它不存在，因此Spring无法注入bean。
