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

你可以删除第一个＆＃34; /＆＃34;从

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

为了拥有：

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

Answer 2

web.xml中使用的标记就是问题。

尝试添加context-param而不是servlet param

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

未找到WebApplicationContext：未注册ContextLoaderListener：java.lang.IllegalStateException
