（参数的注入，如果搞错会获取不到应该得到的参数值及应有的响应值）
struts中：
public String queryA() throws Throwable {
//以下代码用异常块包裹
res = new HashMap<String, Object>(); //res 为全局参数，businessModel, borrowerId都有getset方法,手动注入；
loanQualificationService.queryifUploadProgram(businessModel, borrowerId);
return success;
}
对应的action的配置：
<action name="queryA" class="com.pear.statistic.action.LoanAction" method="queryA">
<result type="json" >
<param name="root">res</param>
</result>
</action>
spring中：
public String queryA(String businessModel,int borrowerId) throws Throwable {
//以下代码用异常块包裹
res = new HashMap<String, Object>(); //全局参数，有getset方法，businessModel, borrowerId自动注入，但需要与页面传来的参数名称一致
loanQualificationService.queryifUploadProgram(businessModel, borrowerId);
}
