crm_parent

除了web需要使用web程序外，其他的都是普通的maven项目

在第一个文件中有需要指定版本号，这样方便以后的修改等等

basic_core

因为需要用到事务所以需要导入事务的包

<dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-tx</artifactId>
            <version>${spring.version}</version>
        </dependency>
    </dependencies>

baisc_util

需要一个分页，及AjaxResoult

AjaxResoult

package cn.jiedada;

public class AjaxResoult {
    private Boolean success=true;
    private String msg="消息正确";

    public Boolean getSuccess() {
        return success;

    public AjaxResoult setSuccess(Boolean success) {
