我的类对象没有转换成json，我认为它返回对象引用，尽管在本地执行它时，它执行得很好。

这是代码

private def static sql

private static List<ProductAlertsResponse> executeSelection(String query)
{
    List<ProductAlertsResponse> prodAlerts=new ArrayList<ProductAlertsResponse>()
    sql.eachRow(query)
    {
        ProductAlertsResponse prodAlert=new ProductAlertsResponse((String)it.id,(String)it.name,(String)it.description,(String)it.active,(String)it.release_date)
        prodAlerts.add(prodAlert)
    }
    return prodAlerts
}

static main(args) {

    AppProperties.load()
    sql = Sql.newInstance("jdbc:oracle:thin:@"+AppProperties.get("hostname")+":"+AppProperties.get("port")+":"+AppProperties.get("service"), AppProperties.get("username"), AppProperties.get("password"),"oracle.jdbc.OracleDriver")

    List<ProductAlertsResponse> sqlResult=executeSelection("select ID,NAME,DESCRIPTION,ACTIVE,RELEASE_DATE from productinfo where ACTIVE='A'")

    def json = new groovy.json.JsonBuilder([response: sqlResult])

    String response=json.toPrettyString()
    println "$response"
}

这给了我以下回复

{
"response": [
    {
        "active": "A",
        "release_date": "2011-09-23 00:00:00.0",
        "id": "1",
        "description": "Test",
        "name": "ABC7"
    },
    {
        "active": "A",
        "release_date": "2012-01-19 00:00:00.0",
        "id": "5",
        "description": "Test1",
        "name": "ABC3"
    },
    {
        "active": "A",
        "release_date": "2011-09-23 00:00:00.0",
        "id": "3",
        "description": "Test",
        "name": "ABC1"
    },
    {
        "active": "A",
        "release_date": "2012-01-19 00:00:00.0",
        "id": "6",
        "description": "Test2",
        "name": "ABC2"
    }
]
}

在我的服务器上运行它（struts和commons链）时，它给我以下json响应（在删除静态后）

{
"response": [
    "com.est.dxclient.common.ProductAlertsResponse@67f797",
    "com.est.dxclient.common.ProductAlertsResponse@1e8f2a0",
    "com.est.dxclient.common.ProductAlertsResponse@c3d9ac",
    "com.est.dxclient.common.ProductAlertsResponse@7d8bb"
]
}

注意： 我正在使用groovy 1.8.0

更新 添加服务器端代码

My server side

class GetProductAlertsResponse implements Command {
//Command is import org.apache.commons.chain.Command
    private def sql

    @Override
    public boolean execute(Context ctx) throws Exception 
    {
        AppProperties.load()
        sql = Sql.newInstance("jdbc:oracle:thin:@"+AppProperties.get("hostname")+":"+AppProperties.get("port")+":"+AppProperties.get("service"), AppProperties.get("username"), AppProperties.get("password"),"oracle.jdbc.OracleDriver")

        List<ProductAlertsResponse> sqlResult=executeSelection("select ID,NAME,DESCRIPTION,ACTIVE,RELEASE_DATE from productinfo where ACTIVE='A'")

        def json = new groovy.json.JsonBuilder([response: sqlResult])

        /*I am trying to debug the code here*/
        println sqlResult.size()

        sqlResult.each{
            println it.getName()
        }

        String response=json.toPrettyString()

        println "Inside commands $response"
        ctx.put(CSMContextParams.response,response)
        return false;

    }
}

在控制台上打印

4
ABC7
ABC3
ABC1
ABC2
Inside commands [
    "com.est.dxclient.common.ProductAlertsResponse@a63599",
    "com.est.dxclient.common.ProductAlertsResponse@156f14c",
    "com.est.dxclient.common.ProductAlertsResponse@9ba632",
    "com.est.dxclient.common.ProductAlertsResponse@bc5245"
]
