Spring 单元测试Struts2+；带刀弹簧动作

我试图对struts2操作进行单元测试（访问一个真实的数据库），但我一直未能成功连接到数据库

我是Spring新手，项目设置在多个bean和DAO类中使用jdbctemplate

以下是我迄今为止的尝试：

测试等级：

    public class Test extends StrutsSpringTestCase {

    private static final String serverURL = "jdbc:db2://xxxx.xxx.com:----/xxxx";
    private static final String username = "xxxxxxx";
    private static final String password = "xxxxxxx";

    @Override
    public String[] getContextLocations() {

    SimpleNamingContextBuilder s = new SimpleNamingContextBuilder();

    DB2SimpleDataSource db=new DB2SimpleDataSource(); 

    try {
    DriverManager.registerDriver( new com.ibm.db2.jcc.DB2Driver() );
    } catch (SQLException e2) {
    // TODO Auto-generated catch block
    e2.printStackTrace();
    }

    try {
    Class.forName("com.ibm.db2.jcc.DB2DataSource");
    } catch (ClassNotFoundException e1) {
    // TODO Auto-generated catch block
    e1.printStackTrace();
    }

    db.setServerName(serverURL);
    db.setPortNumber(----);
    db.setUser(username);
    db.setPassword(password);

    try {

    Hashtable env = new Hashtable();
    env.put(Context.INITIAL_CONTEXT_FACTORY,
     "com.ibm.websphere.naming.WsnInitialContextFactory");
    env.put(Context.PROVIDER_URL, "iiop://xxxx.xxx.com:----");
    Context ctx = new InitialContext(env);

    Context javaCtx = ctx.createSubcontext("jdbc");
    javaCtx.bind("xxx", db);
    ctx.bind("java:", javaCtx);

    } catch (IllegalStateException e) {
    e.printStackTrace();
    } catch (NamingException e) {
    e.printStackTrace();
    }

    String[] locations = new String[1];

    locations[0] = "xxxx.xml";

    return locations;
    }

    public void test() throws Exception {

    ActionProxy proxy = getActionProxy("/test");

    testAction rd = (testAction) proxy.getAction();

    System.out.println(rd.testMethod());

    }
    }

ApplicationContext.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd">

<bean name="jndi" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="jdbc/XXX" />
</bean>

<bean name="dataSource"     class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.ibm.db2.jcc.DB2Driver"/>
<property name="url" value="jdbc:db2://----.---.com:xxxx/xxxx"/>
<property name="username" value="xxxxxxxx"/>
<property name="password" value="xxxxxxxx"/>
</bean>

<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
<constructor-arg>
    <ref bean="dataSource" />
</constructor-arg>

</bean>

<bean id="xxxxDao"
    class="xxxx">
    <property name="jdbcTemplate" ref="jdbcTemplate" />
</bean>

我的applicationContext.xml包含一个数据源和一个JNDIBean，这有点多余。我不知道是否有可能在JdbcTemplate中将两者结合起来，以使连接成功

单独使用数据源会导致缺少元数据/jdbc异常……虽然我想使用jndiobjectfactorybean类，但如果不通过服务器运行它，bean不会在JUnit中初始化

我尝试在JDBCTemplatebean中包含JNDIBean（在调用SimpleNameingContextBuilder之后），这导致了一个匹配的构造函数异常

想法/建议

另外，如果问题格式有点不合适，我很抱歉，我也是stackoverflow新手

jndi bean的Stacktrace错误：

用这个代替你的过去

 <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
    <property name="dataSource" ref="dataSource" />
 </bean>

您能显示堆栈跟踪吗！！我添加了两个StackTrace（在jdbctemplate中使用JNDObjectFactoryBean），它产生的结果与我使用该格式得到的结果相同。测试类不会抛出异常…项目只是从proxy.execute吐回“exception”。我怀疑，由于公司环境的原因，我需要设置一组属性以使数据源连接成功。我将尝试记录一个有用的stacktrace，如果我可以，它如何显示相同的错误。上面的错误指向构造函数参数。尝试清除生成。：）至少解决了构造函数错误。我想+1的建议，但我还没有15个代表。新的错误是什么？？如果问题解决了，接受答案哦，我没有意识到接受和打分是不同的。我显著地更改了测试类……似乎我必须配置初始上下文，以便获取JNDI。通常Websphere处理上下文，所以现在我正尝试复制Websphere正在做的事情。这里只有一个java.nullpointerexception，因为DAO是空的，这是一个放下配置的问题。然后连接就会成功
