我已经使用camel-sql编写了代码,它工作得很好。现在,我必须为同样的问题编写测试用例。我使用了内存中的数据库H2。我已经初始化了数据库并将数据源分配给了sqlComponent。
// Setup code
@Override
protected JndiRegistry createRegistry() throws Exception {
JndiRegistry jndi = super.createRegistry();
// this is the database we create with some initial data for our unit test
database = new EmbeddedDatabaseBuilder()
.setType(EmbeddedDatabaseType.H2).addScript("createTableAndInsert.sql").build();
jndi.bind("myDataSource", database);
return jndi;
}
// Testcase code
@SuppressWarnings("unchecked")
@Test
public void testRoute() throws Exception {
Exchange receivedExchange = template.send("direct:myRoute", ExchangePattern.InOut ,exchange -> {
exchange.getIn().setHeader("ID", new Integer(1));
});
camelContext.start();
MyClass updatedEntity = (MyClass)jdbcTemplate.queryForObject("select * from MY_TABLE where id=?", new Long[] { 1l } ,
new RouteTest.CustomerRowMapper() );
// Here I can get the updatedEntity from jdbcTemplate
assertNotNull(receivedExchange);
assertNotNull(updatedEntity);
}
// Main code
from("direct:myRoute")
.routeId("pollDbRoute")
.transacted()
.to("sql:select * from MY_TABLE msg where msg.id = :#"+ID+"?dataSource=#myDataSource&outputType=SelectOne&outputClass=com.entity.MyClass")
.log(LoggingLevel.INFO,"Polled message from DB");问题是,一旦测试用例开始,它就会说
No bean could be found in the registry for: myDataSource of type: javax.sql.DataSource 我查看了camel-SQL组件测试用例,并执行了相同的操作,但代码无法找到dataSource。请帮帮忙。提前谢谢。

在这个问题上花了很多时间之后,我发现H2数据库正在使用JDBCUtils来获取记录,并且抛出了ClassNotFoundException。我在Camel exception hierarchy中找不到它,因为这个异常被抑制了,所有我都得到了一个通用的异常消息。以下是例外情况:
ClassNotFoundException: com.vividsolutions.jts.geom.Geometry在搜索这个问题之后,我发现它需要更多的依赖项。所以我添加了它,它解决了这个问题。
