S2SH框架搭建—基于XML配置

程序员文章站 2022-07-14 23:45:35
...

此次搭建s2sh框架为本人练手之用,如有不足请见谅,但希望能帮助到大家!

框架采用struts2.3.34、spring4.3.14、hibernate5.1.12版本搭建,jdk版本采用1.6。

框架中所有配置均采用XML方式进行配置。

1、 S2SH框架介绍

Struts:控制层,用来控制的。
Spring:对Struts和Hibernate进行管理,整合的。
Hibernate:操控数据库,持久化操作。

框架优点:
1.spring管理对象的实例化,把对象的创建和获取放到外部,更加的灵活方便。
2.Hibernate避免了JDBC连接数据库的冗余繁杂。
3.各层分工明细,实现了各层之间的解耦,代码更加灵活。

3) spring配置文件applicationContext.xml,以及其他spring配置文件(在applicationContext.xml中引入其他配置文件)。

applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>

    <!-- 
    C3P0数据源:
    	driverClass:数据库驱动;
    	jdbcUrl:数据库连接;
    	user:数据库用户名;
    	password:数据库用户密码;
    	(以上为必须配置的属性)
    	acquireIncrement:当连接池中的连接用完时,C3P0一次性创建新连接的数目,默认为3; 
		acquireRetryAttempts:定义在从数据库获取新连接失败后重复尝试获取的次数,默认为30; 
		acquireRetryDelay:两次连接中间隔时间,单位毫秒,默认为1000; 
		autoCommitOnClose:连接关闭时默认将所有未提交的操作回滚。默认为false; 
		automaticTestTable: C3P0将建一张名为Test的空表,并使用其自带的查询语句进行测试。如果定义了这个参数,那么属性preferredTestQuery将被忽略。
							你不能在这张Test表上进行任何操作,它将中为C3P0测试所用,默认为null; 
		breakAfterAcquireFailure:获取连接失败将会引起所有等待获取连接的线程抛出异常。但是数据源仍有效保留,并在下次调用getConnection()的时候继续尝试获取连接。
								如果设为true,那么在尝试获取连接失败后该数据源将申明已断开并永久关闭。默认为 false; 
		checkoutTimeout:当连接池用完时客户端调用getConnection()后等待获取新连接的时间,超时后将抛出SQLException,如设为0则无限期等待。单位毫秒,默认为0; 
		connectionTesterClassName: 通过实现ConnectionTester或QueryConnectionTester的类来测试连接,类名需设置为全限定名。默认为 com.mchange.v2.C3P0.impl.DefaultConnectionTester; 
		idleConnectionTestPeriod:隔多少秒检查所有连接池中的空闲连接,默认为0表示不检查; 
		initialPoolSize:初始化时创建的连接数,应在minPoolSize与maxPoolSize之间取值。默认为3; 
		maxIdleTime:最大空闲时间,超过空闲时间的连接将被丢弃。为0或负数则永不丢弃。默认为0; 
		maxPoolSize:连接池中保留的最大连接数。默认为15; 
		minPoolSize:连接池中保留的最小连接数
		maxStatements:JDBC的标准参数,用以控制数据源内加载的PreparedStatement数量。但由于预缓存的Statement属于单个Connection而不是整个连接池。
						所以设置这个参数需要考虑到多方面的因素,如果maxStatements与 maxStatementsPerConnection均为0,则缓存被关闭。默认为0; 
		maxStatementsPerConnection:连接池内单个连接所拥有的最大缓存Statement数。默认为0; 
		numHelperThreads:C3P0是异步操作的,缓慢的JDBC操作通过帮助进程完成。扩展这些操作可以有效的提升性能,通过多线程实现多个操作同时被执行。默认为3; 
		preferredTestQuery:定义所有连接测试都执行的测试语句。在使用连接测试的情况下这个参数能显著提高测试速度。测试的表必须在初始数据源的时候就存在。默认为null; 
		propertyCycle: 用户修改系统配置参数执行前最多等待的秒数。默认为300; 
		testConnectionOnCheckout:因性能消耗大请只在需要的时候使用它。如果设为true那么在每个connection提交的时候都 将校验其有效性。
								建议使用idleConnectionTestPeriod或automaticTestTable等方法来提升连接测试的性能。默认为false; 
		testConnectionOnCheckin:如果设为true那么在取得连接的同时将校验连接的有效性。默认为false

		在hibernate5中获取sessionFactory ,
		hibernate3则class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"
		hibernate4则class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"
	设置属性说明:
		hibernate.dialect:设置方言
		hibernate.format_sql:输出格式化的sql
		hibernate.show_sql:控制台输出sql
		hibernate.jdbc.fetch_size:Hibernate每次从数据库中取出并放到JDBC的Statement中的记录条数。FetchSize设的越大,读数据库的次数越少,速度越快,Fetch Size越小,读数据库的次数越多,速度越慢
		hibernate.jdbc.batch_size:Hibernate批量插入,删除和更新时每次操作的记录数。BatchSize越大,批量操作的向数据库发送Sql的次数越少,速度就越快,同样耗用内存就越大
		hibernate.hbm2ddl.auto:自动创建|更新|验证数据库表结构。有以下几个参数: 
		    		create:每次加载hibernate时都会删除上一次的生成的表,然后根据你的model类再重新来生成新表,哪怕两次没有任何改变也要这样执行,这就是导致数据库表数据丢失的一个重要原因。
		    		create-drop:每次加载hibernate时根据model类生成表,但是sessionFactory一关闭,表就自动删除。
		    		update:最常用的属性,第一次加载hibernate时根据model类会自动建立起表的结构(前提是先建立好数据库),以后加载hibernate时根据 model类自动更新表结构,即使表结构改变了
		    				但表中的行仍然存在不会删除以前的行。要注意的是当部署到服务器后,表结构是不会被马上建立起来的,是要等 应用第一次运行起来后才会。
		    		validate :每次加载hibernate时,验证创建数据库表结构,只会和数据库中的表进行比较,不会创建新表,但是会插入新值。
		current_session_context_class:使用缓存机制,配置此处 sessionFactory.getCurrentSession()可以完成一系列的工作,当调用时,hibernate将session绑定到当前线程,
				事务结束后,hibernate将session从当前线程中释放,并且关闭session。当再次调用getCurrentSession()时,将得到一个新的session,并重新开始这一系列工作。
				(hibernate3:Thread或jta);(hibernate4:org.springframework.orm.hibernate4.SpringSessionContext);
				(hibernate5:org.springframework.orm.hibernate5.SpringSessionContext)
		hibernate.cache.use_second_level_cache:是否启用二级缓存,true或false
		hibernate.cache.provider_class:使用Ehcache缓存;hibernate3是org.hibernate.cache.HashtableCacheProvider;hibernate4是net.sf.ehcache.hibernate.EhCacheProvider
		hibernate.cache.use_query_cache:是否启用查询缓存,true或false
		hibernate.temp.use_jdbc_metadata_defaults:Hibernate默认是使用jdbc方式来取的,若使用连接池的方式,将此配置项置为false,否则启动时抛出异常Disabling contextual LOB creation as createClob() method threw error : java.lang.reflect.Invocation

	}
}

7、 Entity,数据库表ORM映射信息,包含hbm文件和实体bean

SysUser.java

package com.folwind.sys.user.entity;

/**
 * SysUser entity. @author MyEclipse Persistence Tools
 */

public class SysUser implements java.io.Serializable {

	// Fields

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	private String id;
	private String password;
	private String realName;
	private String email;
	private String mobile;
	private String orgId;

	// Constructors

	/** default constructor */
	public SysUser() {
	}

	/** minimal constructor */
	public SysUser(String id) {
		this.id = id;
	}

	/** full constructor */
	public SysUser(String id, String password, String realName, String email,
			String mobile, String orgId) {
		this.id = id;
		this.password = password;
		this.realName = realName;
		this.email = email;
		this.mobile = mobile;
		this.orgId = orgId;
	}

	// Property accessors

	public String getId() {
		return this.id;
	}

	public void setId(String id) {
		this.id = id;
	}

	public String getPassword() {
		return this.password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	public String getRealName() {
		return this.realName;
	}

	public void setRealName(String realName) {
		this.realName = realName;
	}

	public String getEmail() {
		return this.email;
	}

	public void setEmail(String email) {
		this.email = email;
	}

	public String getMobile() {
		return this.mobile;
	}

	public void setMobile(String mobile) {
		this.mobile = mobile;
	}

	public String getOrgId() {
		return this.orgId;
	}

	public void setOrgId(String orgId) {
		this.orgId = orgId;
	}

}

SysUser.hbm.xml

            </column>
        </property>
    </class>
</hibernate-mapping>

8、 Service,service层业务逻辑操作,继承BaseService

package com.folwind.sys.user.service;

import java.util.List;

import org.apache.commons.lang.StringUtils;

import com.folwind.framework.core.BaseService;
import com.folwind.sys.user.entity.SysUser;

public class SysUserService extends BaseService<SysUser> {
	public static String BEAN_ID = "user_SysUserService";

	@Override
	public Class<SysUser> getEntityClass() {
		return SysUser.class;
	}

	@Override
	public String getEntityClassName() {
		return "SysUser";
	}

	@Override
	protected String generateWheres(SysUser queryEntity,
			List<String> paramNames, List<Object> values) throws Exception {
		if(queryEntity == null) {
			return "";
		}
		StringBuilder sb = new StringBuilder();
		
		if(StringUtils.isNotBlank(queryEntity.getRealName())) {
			sb.append(" and t.realName like :realName");
			paramNames.add("realName");
			values.add("%" + queryEntity.getRealName() + "%");
		}
		if(StringUtils.isNotBlank(queryEntity.getMobile())) {
			sb.append(" and t.mobile like :mobile");
			paramNames.add("mobile");
			values.add("%" + queryEntity.getMobile() + "%");
		}
		return sb.toString();
	}
}

9、 Action,action层控制逻辑操作,继承BaseActionSupport

package com.folwind.sys.user.action;

import org.apache.commons.lang.StringUtils;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

import com.folwind.framework.core.BaseActionSupport;
import com.folwind.framework.core.BaseService;
import com.folwind.framework.core.PageModel;
import com.folwind.framework.util.PageUtil;
import com.folwind.framework.util.SpringContextUtil;
import com.folwind.sys.user.entity.SysUser;
import com.folwind.sys.user.service.SysUserService;

public class SysUserAction extends BaseActionSupport {

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	private final Log LOG = LogFactory.getLog(SysUserAction.class);

	private SysUser entity;
	private String id;

	public String list() {
		return "list";
	}

	public String search() {
		PageModel pm = null;
		try {
			pm = PageUtil.createPageModel(request);

			pm = getService().findPage(getEntity(), pm);

			pm.setSuccess(Boolean.TRUE);
			pm.setMsg("查询数据成功!");
		} catch (Exception e) {
			if(pm == null) {
				pm = new PageModel();
			}

			pm.setSuccess(Boolean.FALSE);
			pm.setMsg("查询数据失败!");
			LOG.error("查询数据失败!" + e.getMessage(), e);
		}
		setJson(pm);

		return JSON;
	}

	public String searchById() {
		try {
			entity = getService().loadById(id);

			addJson("entity", entity);
			setSuccessJson("查询数据成功!");
		} catch (Exception e) {
			e.printStackTrace();
			setFailJson("查询数据失败!");
			LOG.error("查询数据失败!" + e.getMessage(), e);
		}

		return JSON;
	}

	public String save() {
		try {
			getService().saveOrUpdate(getEntity());

			setSuccessJson("保存数据成功!");
		} catch (Exception e) {
			setFailJson("保存数据失败!");
			LOG.error("保存数据失败!" + e.getMessage(), e);
		}

		return JSON;
	}

	public String delete() {
		try {
			if(StringUtils.isNotBlank(id)) {
				getService().deleteByIds(StringUtils.split(id.toString(), ","));
			}

			setSuccessJson("删除数据成功!");
		} catch (Exception e) {
			setFailJson("删除数据失败!");
			LOG.error("删除数据失败!" + e.getMessage(), e);
		}

		return JSON;
	}

	protected BaseService<SysUser> getService() {
		return (SysUserService) SpringContextUtil.getBean(SysUserService.BEAN_ID);
	}

	public SysUser getEntity() {
		return this.entity;
	}

	public void setEntity(SysUser entity) {
		this.entity = entity;
	}

	public String getId() {
		return id;
	}

	public void setId(String id) {
		this.id = id;
	}

}

10、 前台调用

前台调用Action方法的方式:user_list.do
