篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了springboot-mybatis-plus基本项目框架相关的知识,希望对你有一定的参考价值。

此仅仅为web最基本框架, 统一异常管理、接口统一日志管理。

项目结构:

 注:

修改为如下图,作用是sql打印输出。

以上为jar方式使用ieda内嵌tomcat启动,如果想打包成war包,使用外部tomcat启动需要进行如下修改:

1. 将项目的启动类JarfkApplication.java继承SpringBootServletInitializer并重写configure方法:

package com.jarfk;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

@SpringBootApplication
@MapperScan("com.jarfk.mapper*")
public class JarfkApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(JarfkApplication.class);
    }

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

2. pom.xml中:

    <groupId>com.jarfk</groupId>
    <artifactId>fack</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>

改为:

    <groupId>com.jarfk</groupId>
    <artifactId>fack</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>war</packaging>

新增:

        <!-- 打war包时加入此项, 告诉spring-boot tomcat相关jar包用外部的,不要打进去 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <scope>provided</scope>
        </dependency>

<plugins>里面注释:

            <!-- 如果要打成jar包并使用 java -jar **.jar运行,请不要注释spring-boot-maven-plugin -->
                <!--<plugin>-->
                   <!--<groupId>org.springframework.boot</groupId>-->
                   <!--<artifactId>spring-boot-maven-plugin</artifactId>-->
                <!--</plugin>-->

完成即可。

 如果想使用自定义log4j日志输出,可以如下配置:

1. pom.xml中添加:

        <!-- log4j日志 -->
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>1.7.21</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
            <version>1.7.21</version>
        </dependency>

2. 在resources目录下新建log4j.properties,内容如下:

log4j.rootLogger=DEBUG, stdout
######################### logger ##############################

log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.conversionPattern = %d [%t] %-5p %c - %m%n
#日志级别是INFO,标签是extProfile
log4j.logger.extProfile=DEBUG, extProfile
#输出到指定文件extProfile.log中
log4j.additivity.extProfile=false;

log4j.appender.extProfile=org.apache.log4j.RollingFileAppender
#输出到resin根目录的logs文件夹,log4j会自动生成目录和文件
log4j.appender.extProfile.File=logs/extProfile.log
#超过20M就重新创建一个文件
log4j.appender.extProfile.MaxFileSize=20480KB
log4j.appender.extProfile.MaxBackupIndex=10
log4j.appender.extProfile.layout=org.apache.log4j.PatternLayout
log4j.appender.extProfile.layout.ConversionPattern=%d [%t] %-5p %c - %m%n

完成以上两步即可,以上是 org.apache.log4j.Logger 类型的日志配置。

如果想同时设置 org.slf4j.LoggerFactory 类型日志,可进行如下操作:

application.yml中日志的设置注释掉:

然后再资源目录resources下新建 logback.xml 即可,如下:

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false">
    <!--定义日志文件的存储地址 勿在 LogBack 的配置中使用相对路径-->
    <property name="LOG_HOME" value="/spring-boot-log" />
    <!-- 控制台输出 -->
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <!--格式化输出:%d表示日期,%thread表示线程名,%-5level:级别从左显示5个字符宽度%msg:日志消息,%n是换行符-->
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
            <charset>GBK</charset>
        </encoder>
    </appender>
    <!-- 按照每天生成日志文件 -->
    <appender name="FILE"  class="ch.qos.logback.core.rolling.RollingFileAppender">
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--日志文件输出的文件名-->
            <FileNamePattern>${LOG_HOME}/web.log.%d{yyyy-MM-dd}.log</FileNamePattern>
            <!--日志文件保留天数-->
            <MaxHistory>30</MaxHistory>
        </rollingPolicy>
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <!--格式化输出:%d表示日期,%thread表示线程名,%-5level:级别从左显示5个字符宽度%msg:日志消息,%n是换行符-->
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
            <charset>UTF-8</charset>
        </encoder>
        <!--日志文件最大的大小-->
        <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
            <MaxFileSize>10MB</MaxFileSize>
        </triggeringPolicy>
    </appender>
    <!-- show parameters for hibernate sql 专为 Hibernate 定制 -->
    <logger name="org.hibernate.type.descriptor.sql.BasicBinder"  level="TRACE" />
    <logger name="org.hibernate.type.descriptor.sql.BasicExtractor"  level="DEBUG" />
    <logger name="org.hibernate.SQL" level="DEBUG" />
    <logger name="org.hibernate.engine.QueryParameters" level="DEBUG" />
    <logger name="org.hibernate.engine.query.HQLQueryPlan" level="DEBUG" />

    <!--myibatis log configure-->
    <logger name="com.apache.ibatis" level="TRACE"/>
    <logger name="java.sql.Connection" level="DEBUG"/>
    <logger name="java.sql.Statement" level="DEBUG"/>
    <logger name="java.sql.PreparedStatement" level="DEBUG"/>

    <!-- 日志输出级别 -->
    <root level="DEBUG">
        <appender-ref ref="STDOUT" />
        <appender-ref ref="FILE" />
    </root>
    <!--日志异步到数据库 -->
    <!--<appender name="DB" class="ch.qos.logback.classic.db.DBAppender">-->
    <!--&lt;!&ndash;日志异步到数据库 &ndash;&gt;-->
    <!--<connectionSource class="ch.qos.logback.core.db.DriverManagerConnectionSource">-->
    <!--&lt;!&ndash;连接池 &ndash;&gt;-->
    <!--<dataSource class="com.mchange.v2.c3p0.ComboPooledDataSource">-->
    <!--<driverClass>com.mysql.jdbc.Driver</driverClass>-->
    <!--<url>jdbc:mysql://127.0.0.1:3306/databaseName</url>-->
    <!--<user>root</user>-->
    <!--<password>root</password>-->
    <!--</dataSource>-->
    <!--</connectionSource>-->
    <!--</appender>-->
</configuration>

 

如果此框架中需要在普通类里面注入bean,那么可以在Spring Boot可以扫描的包下新建SpringAutoWriteUtil:

package com.jarfk.util;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

/**
 * 注入bean工具类
 * 注:此类需要在Spring Boot可以扫描的包下
 * Created by Administrator on 2017/9/7.
 */
@Component
public class SpringAutoWriteUtil implements ApplicationContextAware {
    private static ApplicationContext applicationContext = null;
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        if(SpringAutoWriteUtil.applicationContext == null){
            SpringAutoWriteUtil.applicationContext  = applicationContext;
        }
    }
    //获取applicationContext
    private static ApplicationContext getApplicationContext() {
        return applicationContext;
    }
    //通过name获取 Bean.
    public static Object getBean(String name){
        return getApplicationContext().getBean(name);
    }
    //通过class获取Bean.
    public static <T> T getBean(Class<T> clazz){
        return getApplicationContext().getBean(clazz);
    }
    //通过name,以及Clazz返回指定的Bean
    public static <T> T getBean(String name,Class<T> clazz){
        return getApplicationContext().getBean(name, clazz);
    }
}

调用方式:

 

 

附加:整合redis

 1.pom.xml引入两个jar包

        <!-- redis -->
        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>2.9.0</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-redis</artifactId>
            <version>1.8.1.RELEASE</version>
        </dependency>

2.application.yml中配置redis服务

 

3.新建JedisClusterConfig配置类

package com.jarfk.config;

import org.apache.commons.pool2.impl.GenericObjectPoolConfig;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import redis.clients.jedis.HostAndPort;
import redis.clients.jedis.JedisCluster;

import java.util.HashSet;
import java.util.Set;

/**
 * Created by Administrator on 2017/9/25 0025.
 */
@Configuration
@ConditionalOnClass({ JedisCluster.class })
public class JedisClusterConfig {
    @Value("${spring.redis.cache.clusterNodes}")
    private String clusterNodes;
    @Value("${spring.redis.cache.password}")
    private String password;
    @Value("${spring.redis.cache.commandTimeout}")
    private Integer commandTimeout;

    @Bean
    public JedisCluster getJedisCluster() {
        String[] serverArray = clusterNodes.split(",");
        Set<HostAndPort> nodes = new HashSet<>();
        for (String ipPort : serverArray) {
            String[] ipPortPair = ipPort.split(":");
            nodes.add(new HostAndPort(ipPortPair[0].trim(), Integer.valueOf(ipPortPair[1].trim())));
        }
        return new JedisCluster(nodes, commandTimeout, commandTimeout, 2, password, new GenericObjectPoolConfig());
    }
}

4.新建redis服务类RedisClusterCache(后面代码中只需注入该类即可对redis数据库操作)

package com.jarfk.util.redis;

import com.jarfk.util.SerializerUtil;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import redis.clients.jedis.JedisCluster;

/**
 * Created by Administrator on 2017/9/25 0025.
 */
@Component
public class RedisClusterCache {
    @Autowired
    private JedisCluster jedisCluster;
    /**
     * 添加缓存数据
     * @param key
     * @param obj
     * @param <T>
     * @return
     * @throws Exception
     */
    public <T> String putCache(String key, T obj) throws Exception {
        final byte[] bkey = key.getBytes();
        final byte[] bvalue = SerializerUtil.serializeObj(obj);
        return jedisCluster.set(bkey,bvalue);
    }


    /**
     * 添加缓存数据,设定缓存失效时间
     * @param key
     * @param obj
     * @param expireTime 秒
     * @param <T>
     * @throws Exception
     */
    public <T> String putCacheWithExpireTime(String key, T obj, final int expireTime) throws Exception {
        final byte[] bkey = key.getBytes();
        final byte[] bvalue = SerializerUtil.serializeObj(obj);
        String result = jedisCluster.setex(bkey, expireTime,bvalue);
        return result;
    }

    /**
     * 根据key取缓存数据
     * @param key
     * @param <T>
     * @return
     * @throws Exception
     */
    public <T> T getCache(final String key) throws Exception {
        byte[] result = jedisCluster.get(key.getBytes());
        return (T) SerializerUtil.deserializeObj(result);
    }

    /**
     * 根据key删除缓存数据
     * @return
     * @throws Exception
     */
    public void delCache(final String key) throws Exception {
        jedisCluster.del(key.getBytes());
    }
}

 

5. 附加:关于redis集群实现的分布式锁:

http://www.cnblogs.com/007sx/p/7655057.html

 

数据库表:

CREATE TABLE `sys_user` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT,
  `nickname` varchar(20) DEFAULT NULL COMMENT \'用户昵称\',
  `email` varchar(128) DEFAULT NULL COMMENT \'邮箱|登录帐号\',
  `pswd` varchar(32) DEFAULT NULL COMMENT \'密码\',
  `salt` varchar(255) DEFAULT NULL COMMENT \'盐\',
  `create_time` datetime DEFAULT NULL COMMENT \'创建时间\',
  `last_login_time` datetime DEFAULT NULL COMMENT \'最后登录时间\',
  `status` bigint(1) DEFAULT \'1\' COMMENT \'1:有效,0:禁止登录\',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=16 DEFAULT CHARSET=utf8

自行创建,此采用id自增方式,可自行配置。
