后台环境搭建-ssm+maven多模块

2020-02-25 18:03:34 作者：互联网

1.maven多模块的创建

1.1 为什么需要进maven多模块的划分：

如果要写一些公共的模块其他的项目都要使用可以抽取出来
随着项目的越来越大 pom.xml里面内容越来越大，也可以进行抽取到不同的模块里面
编译build 变得越来越长，也要进行划分
如果有些模块不能被人修改，也可单独抽出

1.2 划分模块

maven模块名	放那些内容
basic-util	工具类:Ajaxresult PageList StringUtils
basic-core	基础核心:核心实现 baseMapper baseService baseDomain baseQuery …
crm-common	项目对应的公共东西,domain,query
crm-mapper	映射器,Mapper.java Mapper.xml
crm-service	业务模块
crm1-web	web模块提供数据(接口层)

1.3 模块之间的引用关系

basic_core 引用 basic_util
crm_common 引用 basic_core
crm_common 引用 basic_core 间接引用 basic_util
crm_mapper 引用 crm_common
crm_service 引用 crm_mapper
crm_web 引用 crm_service

1.4 配置文件

web.xml
applicationContext-mvc.xml 写在 crm_web模块
applicationContext.xml 写在 crm_service模块

2.新建一个Maven项目(crm-parent)

在这里插入图片描述

2.1配置pom.xml文件

2.2 创建子模块

在这里插入图片描述

2.3 basic_util模块

用于响应ajax请求信息

package cn.wxy.crm.util;

import lombok.Data;

@Data
public class AjaxResult {
    private Boolean success = true;
    private String message = "操作成功!!!";


    //默认成功
    public AjaxResult() {
    }
    //失败调用
    public AjaxResult(String message) {
        this.success = false;
        this.message = message;
    }

}

用于分页

package cn.wxy.crm.util;

import lombok.Data;

@Data
public class AjaxResult {
    private Boolean success = true;
    private String message = "操作成功!!!";


    //默认成功
    public AjaxResult() {
    }
    //失败调用
    public AjaxResult(String message) {
        this.success = false;
        this.message = message;
    }

}
