java中枚举（enum）小例子。之前学过枚举但是一直没用，这里有个枚举类帮你我理解下（很肤浅）

直接上枚举类，代码简单易懂。

package com.jy.modules.cims.data.interact.tbj.loan.request;

/**

 * @author shengzhoutao

 */
public enum RequestMethodORMEnum {
    /** 接收募集计划申请 */
    METHOD_TBJ_LOAN_RAISE_PLAN {
        public String getRequestMethod() {
            return "tbj.loan.raise.plan";
        }

        public String getServiceMethod() {
            return "doAuditResult";
        }

        public Class<?> getServiceParameterClass() {
            return RequestRaisePlanDTO.class;
        }

        public String getServiceDesc() {
            return "接收募集计划申请";
        }
    },

    /** 接收贷款审批结果 */
    METHOD_TBJ_LOAN_AUDIT_RESULT {
        public String getRequestMethod() {
            return "tbj.loan.audit.result";
        }

        public String getServiceMethod() {
            return "doAuditResult";
        }

        public Class<?> getServiceParameterClass() {
            return RequestAuditResultDTO.class;
        }

        public String getServiceDesc() {
            return "接收贷款审批结果";
        }
    },

    /** 接收贷款放款结果 */
    METHOD_TBJ_LOAN_LOAN_RESULT {
        public String getRequestMethod() {
            return "tbj.loan.loan.result";
        }

        public String getServiceMethod() {
            return "doLoanResult";
        }

        public Class<?> getServiceParameterClass() {
            return RequestLoanResultDTO.class;
        }

        public String getServiceDesc() {
            return "接收贷款放款结果";
        }
    },

    /** 接收产品相关的债权信息 */
    METHOD_TBJ_LOAN_PROD_LOAN {
        public String getRequestMethod() {
            return "tbj.loan.prod.loan";
        }

        public String getServiceMethod() {
            return "doProdLoan";
        }

        public Class<?> getServiceParameterClass() {
            return RequestProdLoanDTO.class;
        }

        public String getServiceDesc() {
            return "接收产品相关的债权信息";
        }
    },

    /** 接收债权匹配信息 */
    METHOD_TBJ_LOAN_TRADE_DEBTOR {
        public String getRequestMethod() {
            return "tbj.loan.trade.debtor";
        }

        public String getServiceMethod() {
            return "doTradeDebtor";
        }

        public Class<?> getServiceParameterClass() {
            return RequestTradeDebtorDTO.class;
        }

        public String getServiceDesc() {
            return null;
        }
    };

    // 获取请求方法
    public abstract String getRequestMethod();

    // 获取请求描述
    public abstract String getServiceDesc();

    // 获取服务方法
    public abstract String getServiceMethod();

    // 获取服务参数Class
    public abstract Class<?> getServiceParameterClass();

}

可以直接调用

RequestMethodORMEnum.METHOD_TBJ_LOAN_AUDIT_RESULT.getServiceDesc();
