Question

我不明白为什么这段代码不起作用。我按照网站的步骤跟踪了指导步骤＆＃34; http://www.tutorialspoint.com/spring/spring_injecting_collection.htm＆＃34;完美。你能帮助我吗？

抛出异常的类：

showPrice

这是调度程序servlet：

public class UserJDBCTemplate implements UserDao {
private DataSource dataSource;
private JdbcTemplate jdbcTemplateObject;

@Override
public void setDataSource(DataSource dataSource) {
    System.out.println(dataSource.toString());
    this.dataSource = dataSource;
    this.jdbcTemplateObject = new JdbcTemplate(dataSource);     
}

public DataSource getDataSource() {
    return dataSource;
}
enter code here
 @Override
public void create(String first_name, String last_name, String role,   

String password, String username, String email, String avatar, String`enter code here` chat_code) {     
    String SQL = "insert into user (first_name, last_name, role, password, username, email, avatar, chat_code) values ( ?, ?, ?, ?, ?, ?, ? , ?)";
    jdbcTemplateObject.update( SQL, first_name, last_name, role, password, username, email, avatar, chat_code);
      //log.info("Created Record Name = " + name + " Age = " + age)     
}

这是contextApplication：

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation=" http://www.springframework.org/schema/beans

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

    </property>
    <property name="suffix">
        <value>.jsp</value>
    </property>
</bean>

这是web.xml文件

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      <property name="username" value="eugen"/>
      <property name="password" value="eugen"/>
   </bean>
   <bean id="addBugJDBCTemplate" class="com.wbm.bug_presents.JDBCTemplate.AddBugJDBCTemplate">

   <bean id="removeBugJDBCTemplate" class="com.wbm.bug_presents.JDBCTemplate.RemoveBugJDBCTemplate">

   <bean id="userJDBCTemplate" class="com.wbm.bug_presents.JDBCTemplate.UserJDBCTemplate">
      <property name="dataSource"  ref="dataSource" />    
   </bean>

错误是：

问题的核心是自我例外：

无法打开ServletContext资源 [/WEB-INF/applicationContext.xml的]

正如您在评论中所写，您的配置文件名为function age(year, month, day) { var today = new Date(); var endDate = new Date(year, month, day).getTime(); var dayDiff = Math.floor((endDate - today) / 86400000); if (dayDiff >= 365) { var year = Math.floor(dayDiff / 365); var remainder = Math.floor(dayDiff) - (year * 365); var months = Math.floor(remainder / 30); } else { var year = 0; var remainder = Math.floor(dayDiff) - (year * 365); var months = Math.floor(remainder / 30); } var days = Math.floor(remainder) - (months * 30); return year + " years" + " " + months + " months" + " " + days + " days"; } document.write("<p>" + age(2017, 11, 17) + "</p>"); document.write("<p>" + age(2016, 7, 11) + "</p>");，因此您必须将其更改为contextApplication.xml。

Spring JDBC，无法打开ServletContext资源
