基于注解搭建spring+springmvc+hibernate

maven依赖：

新建maven项目就不写了。。。

2.建立相关的java替代xml配置

a.新建一个WebAppIntializer类，对应的是web.xml文件

新建一个webAppIntializer类继承AbstractAnnotationConfigDispatcherServletInitializer,容器在启动时会自动扫描是否有类继承了这个抽象类，如果有则用它来配置servlet容器。

public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

        /*
         * 对应的是spring的配置文件,这个文件在下边
         */
        @Override
        protected Class[] getRootConfigClasses() {
                // TODO Auto-generated method stub
                return new Class[]{RootConfig.class};
        }
       
        /*
        *对应的也是配置文件，这个文件也在下边
        */
        @Override
        protected Class[] getServletConfigClasses() {
                // TODO Auto-generated method stub
                return new Class[]{WebConfig.class};
        }
        
        /*
         * 将DispathcerServlet映射到"/"里
         */
        @Override
        protected String[] getServletMappings() {
                // TODO Auto-generated method stub
                return new String[]{"/"};
        }

}

b.RootConfig：

//这里的basepackages里设置的是扫描路径。
@Configuration
@ComponentScan(basePackages={"com.senninha.spring.annotation4mvc","com.senninha.spring.controler"},
                excludeFilters = {@Filter(type = FilterType.ANNOTATION,value = EnableWebMvc.class)})
public class RootConfig {

}

c.WebConfig:

@Configuration
@EnableWebMvc
@ComponentScan("com.senninha.spring.annotation4mvc")
public class WebConfig extends WebMvcConfigurerAdapter{
        //配置jsp视图解析器
        @Bean
        public ViewResolver viewResolver(){
                InternalResourceViewResolver resolver = new InternalResourceViewResolver();
                resolver.setPrefix("/WEB-INF/pages/");
                resolver.setSuffix(".jsp");
                resolver.setExposeContextBeansAsAttributes(true);
                return resolver;
        }
        
        
        @Override
        public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
                // TODO Auto-generated method stub
                //配置静态资源处理
                configurer.enable();;
        }
        
        //这里可以配置自定义的拦截器
        @Override
        public void addInterceptors(InterceptorRegistry registry) {
        // TODO Auto-generated method stub
            registry.addInterceptor(xxxx));
        }
        
        /*
         *夸鱼访问支持，前后端分离开发时用得到
         */
        @Override
        public void addCorsMappings(CorsRegistry registry) {
        // TODO Auto-generated method stub
            registry.addMapping("*").allowedOrigins("*");
        }
}

关于拦截器的文章在这里可以看到springmvc拦截器

3建立一个简单的controller吧（对应Servlet)

//记得要把所在包加入扫描路径
@Controller
@Scope("prototype")
public class UploadController {

    //这里是访问的路径/test
    @RequestMapping(value = "/test")
    public String test() {
        //对应的是test.jsp视图
        return "test";
    }

访问loaclhost:8080/项目名/test 就可以转发到定义的那个test.jsp视图了。

以上已经建立了springmvc + spring 的web项目了，下面加上hiberante和druid连接池,由于没找到怎么配置hibernate的注解，就只好用xml了。。。

3.引入配置文件：

db.properties文件

jdbc.driver=com.mysql.jdbc.Driver
#jdbc.url=jdbc:mysql://localhost:3306/esmp?characterEncoding=utf-8
jdbc.url=jdbc:mysql://127.0.0.1:3306/senninha?autoReconnect=true&useSSL=false&autoReconnectForPools=true&useUnicode=true&characterEncoding=UTF-8

#druid\u76d1\u63a7
jdbc.pool.filters=stat,log4j
jdbc.pool.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000

引入xml文件：

    
    
    
    
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
        
    

    
    
        
        
        
            
            com.senninha.*.orm
        
        
            
                ${hibernate.hbm2ddl.auto}
                ${hibernate.dialect}
                ${hibernate.show_sql}
                ${hibernate.format_sql}
            
        
    
    
    
    
        
    
        
    
    
    

然后在b.RootConfig.java里引入这个xml配置文件：

@Configuration
@ComponentScan(basePackages={"com.senninha.spring.annotation4mvc","com.senninha.spring.controler"},
                excludeFilters = {@Filter(type = FilterType.ANNOTATION,value = EnableWebMvc.class)})
 @ImportResource(value = {"classpath:applicationContext-dao.xml"})
public class RootConfig {

}

然后在符合com.senninha.*.orm路径的包下建立实体类即可自动建表(数据库要先用sql建好 create database senninha character set=utf8)

@Entity
@Table(name = "admin_login", catalog = "senninha")
public class AdminLogin implements Serializable {
    private int id;
    private String password;
    private String salt;
    private Date lastLoginTime;
    
    @Column(name = "id" ,unique = true)
    @Id
    @GeneratedValue(strategy = IDENTITY)
    public int getId() {
        return id;
    }
    
    @Column(name = "password" , length = 64)
    public String getPassword() {
        return password;
    }
    
    @Column(name = "salt" , length = 10)
    public String getSalt() {
        return salt;
    }
    
    @Column(name = "last_login_time")
    public Date getLastLoginTime() {
        return lastLoginTime;
    }
    

    public void setId(int id) {
        this.id = id;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public void setSalt(String salt) {
        this.salt = salt;
    }
    public void setLastLoginTime(Date lastLoginTime) {
        this.lastLoginTime = lastLoginTime;
    }
}

对应数据库的操作应该有dao层，service层（实物注解放在这里）

dao

@Repository
public class Dao{
    
    @Autowired
    private SessionFactory sessionFactory;

    @Override
    public int add(AdminLogin login) {
        // TODO Auto-generated method stub
        int flag=0;
        try{
            Session session=sessionFactory.getCurrentSession();
            session.save(login);
            flag=1;
        }catch(Exception e){
            e.printStackTrace();
        }
        return flag;
    }

service

@Service
@Transactional(rollbackFor=Exception.class)
public class  Service{
    
    @Autowired
    private Dao dao;

    @Override
    public int add() {
        // TODO Auto-generated method stub
        AdminLogin login = new AdminLogin();
        //设置属性
        login.setxxxx...
        dao.add(login);
        return 1;
    }

至于谁来调用service呢，contoller那里的test就可以

@Controller
@Scope("prototype")
public class UploadController {
    @Autowired
    private Service service;
    //这里是访问的路径/test
    @RequestMapping(value = "/test")
    public String test() {
        //对应的是test.jsp视图
        service.add();
        return "test";
    }

至此就搭建完啦。
