SSH的注解整合

1, 引开发必要的jar包

• 注意:引入struts的注解的开发包
  struts2-convention-plugin-2.3.24.jar

2, 引入配置文件

• 注解开发省略了struts.xml配置文件 和hibernate.hbm.xml配置文件

• web.xml

 <!-- 配置Spring核心监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>

    <!-- 配置Struts2的核心过滤器 -->
    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

• log4j.properties

### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.err
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### direct messages to file mylog.log ###
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=c\:mylog.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### set log levels - for more verbose logging change 'info' to 'debug' ###

log4j.rootLogger=info, stdout

• jdbc.properties

jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql:///数据库的名字
jdbc.username=用户名
jdbc.password=密码

3, 创建包和类,引入前端页面

4, 具体的注解添加

Action

• 类上

// Spring的Bean的配置
@Controller("customerAction")
@Scope("prototype")
// Struts2的页面跳转配置
@ParentPackage("struts-default")
@Namespace("/")
public class CustomerAction extends ActionSupport implements ModelDriven< Customer>

• 方法上

@Action(value="customer_save",results={@Result(name="success",location="/jsp/customer/add.jsp")})
    public String save(){
        return SUCCESS;
    }

Service

@Service("customerService")
@Transactional
public class CustomerServiceImpl implements CustomerService {}

Dao

@Repository("customerDao")
public class CustomerDaoImpl extends HibernateDaoSupport implements CustomerDao {}

实体类的注解开发(省去hibernate.hbm.xml)

@Entity // 实体的注解
@Table(name="cst_customer_anno")
public class Customer {
    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private Long cust_id;
    //@Column(name="cust_name")
    private String cust_name;
    private String cust_source;
    private String cust_level;
    private String cust_industry;
    private String cust_phone;
    private String cust_mobile;
}
