ssh项目使用注解搭建

使用struts的注解的话要添加依赖struts2-convention-plugin

  <dependency>
          <groupId>org.apache.struts</groupId>
          <artifactId>struts2-convention-plugin</artifactId>
          <version>${struts.version}</version>
      </dependency>

具体和非注解的区别就是声明的bean直接使用注解方式注入,strust的访问路径和返回路径使用的是注解的方式,就可以省去struts.xml文件
下面可以删除struts.xml文件了,在spring的配置文件中添加扫描控制器的路径

   <context:component-scan base-package="com.chen"/>
      <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="url" value="jdbc:mysql://localhost:3306/sopping?useUnicode=true&amp;characterEncoding=UTF-8&amp;serverTimezone=UTC"></property>
        <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
        <property name="username" value="root"></property>
        <property name="password" value="chen"></property>
    </bean>
      <!--设置hibernate的属性-->
    <bean id="properties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
            <property name="properties" >
                <props>
                    <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                    <prop key="show_sql">true</prop>
                </props>
            </property>
    </bean>

     <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <property name="hibernateProperties" ref="properties"></property>
        <property name="packagesToScan" value="com.chen.entity"></property>
    </bean>
    <bean id="dao" class="com.chen.dao.DaoImpl">
        <property name="sessionFactory" ref="sessionFactory"></property>
    </bean>

然后就可以到我们的控制器中使用注解方式进行配置访问路径

@Controller
@Namespace("/")
@Scope("prototype")
public class LoginAction {
    @Resource
    public ILoginService service;
    public GouwucheEntity gouwucheEntity;
    public List<GouwucheEntity> list;
    @Action(value = "loginQuery",results = {@Result(name = "login",location = "/index.jsp")})
    public String query() {
        System.out.println("登陆方法");
        list=service.queryAll("select gouwucheid,zongjia from GouwucheEntity");
        System.out.println(list);
        return "login";
    }

    public List<GouwucheEntity> getList() {
        return list;
    }

    public void setList(List<GouwucheEntity> list) {
        this.list = list;
    }
}

service类中我们也要使用注解

@Service
public class LoginServiceImpl implements ILoginService {
    @Resource
    private IDao dao;
    @Override
    public List<GouwucheEntity> queryAll(String s) {
        return dao.queryAll(s);
    }
}

dao的实现类使用注解的话会报错sessionFactory没有注入,所以这里在spring的配置文件中进行注入了sessionFactory

public class DaoImpl extends HibernateDaoSupport implements IDao{
    @Override
    public List queryAll(String hql) {
        return getHibernateTemplate().find(hql);
    }
    public Object queryById(String entityName,String id){
        return getHibernateTemplate().get(entityName,id);
    }
    public void add(Object entity){
        getHibernateTemplate().save(entity);
    }
    public void edit(Object entity){
        getHibernateTemplate().update(entity);
    }
}

完成之后我们要访问上面的控制器的话路径就是
localhost:8080/loginQuery.action
