1.WEB.XML

<servlet> 
    <servlet-name>jlcindia</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
    <init-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value>/WEB-INF/config/jlcindia-servlet.xml</param-value> 
    </init-param> 
    <load-on-startup>1</load-on-startup> 
</servlet> 

<servlet-mapping> 
    <servlet-name>jlcindia</servlet-name> 
    <url-pattern>*.do</url-pattern> 
</servlet-mapping> 

2.jlcindia-servlet.xml中

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
    <property name="driverClassName" value="com.mysql.jdbc.Driver" /> 
    <property name="url" value="jdbc:mysql://localhost:3306/ankur" /> 
    <property name="username" value="root" /> 
    <property name="password" value="admin" /> 
</bean> 

<bean id="sessionFactory" 
    class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> 
    <property name="dataSource" ref="dataSource" /> 
    <property name="annotatedClasses"> 
     <list> 
      <value>com.vivek.model.Student</value> 
     </list> 
    </property> 
    <property name="hibernateProperties"> 
     <props> 
      <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> 
      <prop key="hibernate.show_sql">true</prop> 
      <prop key="hibernate.hbm2ddl.auto">update</prop>     
     </props> 
    </property> 
</bean> 

<bean id="hibernateTransactionManager" 
    class="org.springframework.orm.hibernate3.HibernateTransactionManager"> 
    <property name="sessionFactory" ref="sessionFactory" /> 
</bean> 

控制器类：

@Controller 
public class StudentController { 

@Autowired 
private StudentService studentService; 

public String setupForm(Map <String,Object> map){ 

    System.out.println("setupForm() -> StudentController Called"); 

    Student student=new Student(); 
    map.put("student",student); 
    map.put("studentList",studentService.getAllstudent()); 
    return "student"; 

} 

@RequestMapping(value="/student.do", method=RequestMethod.POST) 
public String doActions(@ModelAttribute Student student,BindingResult result,@RequestParam String actions,Map <String,Object> map){ 

    System.out.println("doActions() -> StudentController Called"); 

    Student studentresult=new Student(); 
    switch (actions.toLowerCase()) { 
    case "add": 
     studentService.add(student); 
     studentresult=student; 

    case "edit": 
     studentService.edit(student); 
     studentresult=student; 

    case "delete": 
     studentService.delete(student.getStudentId()); 
     studentresult=new Student(); 
    case "search": 

     Student searchStudent=studentService.getStudent(student.getStudentId()); 
     studentresult = searchStudent!=null ? searchStudent : new Student(); 
     break; 
    default: 
     break; 
    } 

    map.put("student",studentresult); 
    map.put("student",studentService.getAllstudent()); 

    return "student"; 
     } 
} 

Answer 1

您可以删除第一个 “/” 从

<param-value>/WEB-INF/config/jlcindia-servlet.xml</param-value> 

为了有：

<param-value>WEB-INF/config/jlcindia-servlet.xml</param-value> 

Answer 2

中使用的标签web.xml是问题。

试的context-param而不是servlet的PARAM

<context-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value> </param-value> 
</context-param>
