springboot搭建ssm项目并配置log4j实现日志记录

作者: haiyong6 | 来源:发表于2019-11-07 22:58 被阅读0次

前边文章写了如何从0搭建ssm 普通web项目，链接：https://www.jianshu.com/p/b84ee274234f
配置环境什么的比较复杂，但是很有掌控感，springboot基本上是在ssm的基础上做了封装，约定优于配置，大大减少了配置项目的时间，但一些东西不在面上总觉得不太习惯，来搭建一个简单的基于springboot2的ssm项目

下载sts工具

打开springboot官网
https://spring.io/projects/spring-boot

点击最下面的tools进入sts工具下载页面，可以选择相应系统版本

sts其实是安装了sts4插件的eclipse，所以也可以用普通的eclipse直接marketPlace搜索下载sts4

用sts工具新建springboot项目

打开sts工具，new一个springboot项目，如图，一路next

上图中把type改为jar包，直接用springboot内置的tomcat启动项目，不用额外下载tomcat服务器了

上图中Available里面可以搜索所有引入模块，这里我们搜索选中搭建ssm项目所需要的mybatis,oracle,thymeleaf,spring web等模块，没错，springboot推荐使用thymeleaf而不是jsp,配置jsp需要额外配置，这里也不建议，作为模板引擎thymeleaf会更强大。

点击finish等待maven下载依赖jar包工程构建完成即可。

application.properties加入以下必须配置项，配置数据源，服务器端口等必须信息

server.port=8081

spring.datasource.url=jdbc\:oracle\:thin\:@127.0.0.1\:1521\:xe
spring.datasource.username=XXXX
spring.datasource.password=XXXX
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver
#spring.datasource.hikari.auto-commit=false


mybatis.config-location=classpath:mybatis/mybatis-config.xml
mybatis.mapper-locations=classpath:mapper/*Mapper.xml

#thymeleaf
spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.html
spring.thymeleaf.mode=LEGACYHTML5
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.servlet.content-type=text/html
spring.thymeleaf.cache=false

logging.config=classpath:log4j2-spring.xml

pom.xml引入log4j依赖，springboot热部署，阿里巴巴的json依赖等

src/main/resource下建立log4j的配置文件 log4j2-spring.xml

<?xml version="1.0" encoding="UTF-8"?>

在resources下建立mybatis文件夹以及mybatis-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">

    </mappers> -->
    <!-- <settings>
        <setting name="logImpl" value="STDOUT_LOGGING"/>
    </settings> -->
</configuration>

resources下建立mapper文件夹以及testMapper.xml

<?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.zhaohy.app.dao.TestMapper">
    <select id="getUser" resultType="java.util.HashMap">
        select * from da_user
    </select>
</mapper>

建立controller,service,serviceImpl,dao等业务层

TestController.java

package com.zhaohy.app.controller;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.zhaohy.app.service.TestService;

@Controller
public class TestController {
    @Autowired
    TestService testService;
    @RequestMapping("/test.do")
    public String test() {
        Map<String, Object> paramsMap = new HashMap<String, Object>();
        List<Map<String, Object>> list = testService.getUser(paramsMap);
        for(int i = 0; i < list.size(); i++) {
            Map<String, Object> map = list.get(i);
            System.out.println(map.get("USER_NAME").toString());
        }
        return "pages/hello.html";
    }
    
    @RequestMapping("/")
    public String goPage() {
        
        
        
        return "index.html";
    }
}

TestService.java

package com.zhaohy.app.service;

import java.util.List;
import java.util.Map;

public interface TestService {

    List<Map<String, Object>> getUser(Map<String, Object> paramsMap);

}

TestServiceImpl.java

package com.zhaohy.app.service.impl;

import java.util.List;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.zhaohy.app.dao.TestMapper;
import com.zhaohy.app.service.TestService;
@Service("TestService")
public class TestServiceImpl implements TestService {
    @Autowired
    private TestMapper testMapper;
    @Override
    public List<Map<String, Object>> getUser(Map<String, Object> paramsMap) {
        
        return testMapper.getUser(paramsMap);
    }

}

TestMapper.java

package com.zhaohy.app.dao;

import java.util.List;
import java.util.Map;

public interface TestMapper {

    List<Map<String, Object>> getUser(Map<String, Object> paramsMap);

}

SpringbootSsmApplication.java里配置mybatis扫描mapper接口路径

package com.zhaohy.app;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@MapperScan("com.zhaohy.app.dao")
public class SpringbootSsmApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootSsmApplication.class, args);
    }

}

src/main/resources/templates下面新建pages文件夹以及所需html

/pages/hello.html

<!DOCTYPE html>
<html  xmlns:th="http://www.thymeleaf.org" >
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
  hello a
</body>
</html>

templates下的index.html

<!DOCTYPE html>
<html  xmlns:th="http://www.thymeleaf.org" >
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
        hello world!
        <div th:text="你好啊">sdf</div>
</body>
</html>

至此项目搭建完毕目录如图
