java - 修复命名空间问题后出现 BeanCreationException

Question

这是 org.xml.sax.SAXParseException;cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found 的后续问题该问题中的问题已解决，但我现在看到 BeanCreationException 在我进行更改之前正在运行的内容。

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'employeeService': Injection of autowired dependencies failed; nested exception is 
org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.springframework.mail.SimpleMailMessage com.xxx.service.EmployeeService.templateMessage; nested exception is 
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.mail.SimpleMailMessage] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

我的 REST Controller 是这样注释的

@RestController
public class EmployeeController

还有我的服务

@Service("employeeService")
public class EmployeeService

在您的 applicationContext xml 文件中添加此/类似内容。

<bean id="simpleMailMessage"
    class="org.springframework.mail.SimpleMailMessage">

    <property name="from" value="from@no-spam.com" />
    <property name="to" value="to@no-spam.com" />
    <property name="subject" value="Testing Subject" />
    <property name="text">
       <value>
        <![CDATA[
            Dear %s,
            Mail Content : %s
        ]]>
       </value>
        </property>
</bean>
