Linux部署項目訪問window系統下的mysql數據庫

一、linux環境搭建

VM14 安裝Linux虛擬機(CentOS-7-x86_64-DVD-1810.iso)，選擇帶GUI圖形界面安裝，虛擬機網絡選擇橋接模式，Linux需要允許網絡連接

1、安裝tomcat8

下載apache-tomcat-8.5.40.tar.gz，使用winSCP拖放到/usr/local目錄下並解壓：
解壓命令： tar zxvf apache-tomcat-8.5.40.tar.gz
解壓完成後，將解壓出來的文件夾名稱改爲tomcat8

2、安裝jdk(也可使用系統自帶的open jdk)

3、Linux防火牆設置

從windows訪問部署在linux環境的項目，需要設置防火牆，我使用的是8080端口，命令如下：
firewall-cmd --zone=public --add-port=8080/tcp --permanent

到此我們Linux環境部署完成

---

二、Windows防火牆設置

1、由於我是從Linux訪問Windows數據庫，同樣不能直接訪問，需要開啓防火牆，mysql的端口爲3306：

windows下：控制面板—>系統和安全—>Windows Defender 防火牆—高級設置：






至此windows的防火牆設置完成

三、測試項目

完整的項目結構：

entity:

package com.sunny.mylogs.entity;

/**
 * @author sunny
 * @create 2019/4/20 18:57
 */
public class Person {

    private int id;

    private String name;

    private int age;

    private String sex;

    public Person() {
    }

    public Person(int id, String name, int age, String sex) {
        this.id = id;
        this.name = name;
        this.age = age;
        this.sex = sex;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    @Override
    public String toString() {
        return "Person{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", age=" + age +
                ", sex='" + sex + '\'' +
                '}';
    }
}

PersonMapper :

package com.sunny.mylogs.dao;


import com.sunny.mylogs.entity.Person;
import org.apache.ibatis.annotations.Mapper;

import java.util.List;

@Mapper
public interface PersonMapper {

    List<Person> getPerson();
}

mapper文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.sunny.mylogs.dao.PersonMapper">

    <!-- 通用查詢映射結果 -->
    <resultMap id="BaseResultMap" type="com.sunny.mylogs.entity.Person">
        <id column="id" property="id" />
        <result column="name" property="name" />
        <result column="age" property="age" />
        <result column="sex" property="sex" />
    </resultMap>

    <!-- 通用查詢結果列 -->
    <sql id="Base_Column_List">
        id, name, age, sex
    </sql>

    <select id="getPerson" resultType="com.sunny.mylogs.entity.Person">
        select <include refid="Base_Column_List"/>  from person
    </select>

</mapper>

service接口 PersonService :

package com.sunny.mylogs.service;

import com.sunny.mylogs.entity.Person;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public interface PersonService {
    List<Person> getPerson();
}

service實現

package com.sunny.mylogs.service.Impl;

import com.sunny.mylogs.dao.PersonMapper;
import com.sunny.mylogs.entity.Person;
import com.sunny.mylogs.service.PersonService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

/**
 * @author sunny
 * @create 2019/4/20 19:10
 */
@Service
public class PersonServiceImpl implements PersonService {

    @Autowired
    private PersonMapper mapper;

    @Override
    public List<Person> getPerson() {
        return mapper.getPerson();
    }
}

controller PersonController :

package com.sunny.mylogs.controller;

/**
 * @author sunny
 * @create 2019/4/20 19:12
 */

import com.sunny.mylogs.entity.Person;
import com.sunny.mylogs.service.PersonService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController
@RequestMapping("/Person")
public class PersonController {

    @Autowired
    private PersonService service;

    @RequestMapping("/getList")
    public List<Person> getPerson(){

        return service.getPerson();

    }

    @RequestMapping("/print")
    public void print(){
        System.out.println("print mylog");
    }
}

至此，項目代碼完成。
然後打包（war）,將war包拖放到/usr/local/tomcat8/webapps/下
執行命令：cd /usr/local/tomcat8/bin
接着執行: ./startup.sh

[root@localhost ~]# cd /usr/local/tomcat8/bin/
[root@localhost bin]# ./startup.sh 
Using CATALINA_BASE:   /usr/local/tomcat8
Using CATALINA_HOME:   /usr/local/tomcat8

Using JRE_HOME:        /usr
Using CLASSPATH:       /usr/local/tomcat8/bin/bootstrap.jar:/usr/local/tomcat8/bin/tomcat-juli.jar
Tomcat started.

在windows瀏覽器中輸入地址：http://xxxxxx:8080/mylog/Person/getList
其中xxxxxx代表linux的IP地址
