理解String 及 String.intern() 在实际中的应用
这个文章的关注点是如何在只准使用servlet jsp jdbc的情况下 加入spring来简化 jdbc代码 事务控制 依赖注入

WebFilter.java
package test.spring;
import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
public class WebFilter implements Filter {
private ManageSupport manageSupport;
public void destroy() {
// TODO Auto-generated method stub
}
public void doFilter(ServletRequest arg0, ServletResponse arg1, FilterChain arg2) throws IOException, ServletException {
System.out.println(getClass().getName() + " filter");
System.out.println(manageSupport.getName());
int count = manageSupport.getJdbcTemplate().queryForInt("SELECT COUNT(*) FROM MESSAGE");
System.out.println(count);
arg2.doFilter(arg0, arg1);
HttpServletRequest req = (HttpServletRequest) arg0;
req.getSession().getServletContext().getRequestDispatcher("/index2.jsp").forward(arg0, arg1);
}
public void init(FilterConfig arg0) throws ServletException {
// TODO Auto-generated method stub
}
public ManageSupport getManageSupport() {
return manageSupport;
}
public void setManageSupport(ManageSupport manageSupport) {
this.manageSupport = manageSupport;
}
}
ManageSupport.java
package test.spring;
import org.springframework.jdbc.core.simple.SimpleJdbcTemplate;
public class ManageSupport{
private SimpleJdbcTemplate jdbcTemplate;
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public SimpleJdbcTemplate getJdbcTemplate() {
return jdbcTemplate;
}
public void setJdbcTemplate(SimpleJdbcTemplate jdbcTemplate) {
this.jdbcTemplate = jdbcTemplate;
}
}
事物控制在spring的sample里有参考
研究了一下事物
改动如下
打算针对ManageSupport做自动事物切入
把ManageSupport重构出接口 用eclipse可以在几秒实现这个
package test.spring;
import org.springframework.jdbc.core.simple.SimpleJdbcTemplate;
public interface IManageSupport {
public abstract String getName();
public abstract void setName(String name);
public abstract SimpleJdbcTemplate getJdbcTemplate();
public abstract void setJdbcTemplate(SimpleJdbcTemplate jdbcTemplate);
public int logic1();
public void logic2();
}
在实现中的事物逻辑
public int logic1(){
return getJdbcTemplate().queryForInt("SELECT COUNT(*) FROM JB_COM_MESSAGE");
}
public void logic2(){
int count=logic1();
for (int i = 1; i <= count; i++) {
getJdbcTemplate().update("update JB_COM_MESSAGE set m_level =1 where id=?", i);
}
}
调用业务方法的方法 WebFilter.java中的
public void doFilter(ServletRequest arg0, ServletResponse arg1, FilterChain arg2) throws IOException, ServletException {
System.out.println(getClass().getName() + " filter");
System.out.println(manageSupport.getName());
int count = manageSupport.logic1();
System.out.println(count);
manageSupport.logic2();
arg2.doFilter(arg0, arg1);
HttpServletRequest req = (HttpServletRequest) arg0;
req.getSession().getServletContext().getRequestDispatcher("/index2.jsp").forward(arg0, arg1);
}
spring配置中 事务相关
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="net.sourceforge.jtds.jdbc.Driver" /> <property name="url" value="jdbc:jtds:sqlserver://127.0.0.1:1433/DSO" /> <property name="username" value="sa" /> <property name="password" value="sa" /> </bean> <aop:config> <aop:advisor pointcut="execution(* test.spring.IManageSupport.*(..))" advice-ref="txAdvice" /> </aop:config> <tx:advice id="txAdvice"> <tx:attributes> <tx:method name="logic*" propagation="REQUIRED" /> </tx:attributes> </tx:advice>
最后执行成功 以下是log
