我正在尝试单元测试struts2操作（命中真正的数据库），但我无法成功连接到数据库 .
我是Spring的新手，项目设置在多个bean和DAO类中使用jdbctemplate .
这是我到目前为止的尝试：
测试类：
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中：
<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:p="http://www.springframework.org/schema/p"
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>
（继续使用其他与DAO相关的bean） .
许多类依赖于JdbcTemplate，如下所示，所以我想找到一个包含它的解决方案：
private JdbcTemplate jdbcTemplate;
private String schemaName = "xxxxxx";
private String procedureName = "xxxxxx";
public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
this.jdbcTemplate = jdbcTemplate;
}
public RDResponseBO browseRD(RDRequestBO rdReqBO) {
SimpleJdbcCall storedProc = new SimpleJdbcCall(jdbcTemplate)
.withSchemaName(schemaName)
.withoutProcedureColumnMetaDataAccess().withProcedureName(
procedureName); .........
我的applicationContext.xml包含一个数据源和一个jndi bean，这有点多余 . 我不知道是否可以在JdbcTemplate中将它们组合在一起以便连接成功 .
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，但是在没有通过服务器运行它的情况下，bean不会在JUnit中初始化 .
我尝试在jdbctemplate bean中包含jndi bean（在调用simplenamingcontextbuilder之后），这导致匹配的构造函数异常 .
/建议的想法？
附：如果问题格式有点偏，我很抱歉，我也是stackoverflow的新手 .
