SpringBoot+MyBatis(generator)+druid整合

最近自己写了一个SpringBoot2.0.2+Mybatis（generator）+druid的demo

首先实现的是mybatis和generator逆向工程生成代码

1.pom文件如下，引入generator插件

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

2.在resources下新建generator文件夹，在generator下新建generatorConfig.xml

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

<!DOCTYPE generatorConfiguration

PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"

"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd" >

< generatorConfiguration >

< context id ="DB2Tables" targetRuntime ="MyBatis3" >

< commentGenerator >

< property name ="suppressDate" value ="true" />

< property name ="suppressAllComments" value ="true" />

</ commentGenerator >

< jdbcConnection driverClass ="com.mysql.jdbc.Driver" connectionURL ="jdbc:mysql://localhost:3306/wordimg" userId ="root" password ="root" >

</ jdbcConnection >

< javaTypeResolver >

< property name ="forceBigDecimals" value ="false" />

</ javaTypeResolver >

< javaModelGenerator targetPackage ="com.cnooc.pojo" targetProject ="src/main/java" >

< property name ="trimStrings" value ="true" />

</ javaModelGenerator >

< sqlMapGenerator targetPackage ="mapper" targetProject ="src/main/resources" >

</ sqlMapGenerator >

<!--

-->

< javaClientGenerator type ="XMLMAPPER" targetPackage ="com.cnooc.dao" targetProject ="src/main/java" >

< property name ="enableSubPackages" value ="true" />

</ javaClientGenerator >

< table tableName ="t_file" domainObjectName ="TFile" enableCountByExample ="false" enableUpdateByExample ="false" enableDeleteByExample ="false" enableSelectByExample ="false" selectByExampleQueryId ="false" ></ table >

< table tableName ="t_file_images" domainObjectName ="TFileImages" enableCountByExample ="false" enableUpdateByExample ="false" enableDeleteByExample ="false" enableSelectByExample ="false" selectByExampleQueryId ="false" ></ table >

</ context >

</generatorConfiguration>

3.运行generator插件

4.生成如下目录

5.application.yml中的配置其中包括对druid的配置

spring:

datasource:

url: jdbc:mysql://localhost:3306/wordimg?useUnicode=true&characterEncoding=utf-8&useSSL=false

username: root

password: root

driver-class-name: com.mysql.jdbc.Driver

platform: mysql

type: com.alibaba.druid.pool.DruidDataSource

# 下面为连接池的补充设置，应用到上面所有数据源中

# 初始化大小，最小，最大

initialSize: 1

minIdle: 3

maxActive: 20

# 配置获取连接等待超时的时间

maxWait: 60000

# 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒

timeBetweenEvictionRunsMillis: 60000

# 配置一个连接在池中最小生存的时间，单位是毫秒

minEvictableIdleTimeMillis: 30000

validationQuery: select 'x'

testWhileIdle: true

testOnBorrow: false

testOnReturn: false

# 打开PSCache，并且指定每个连接上PSCache的大小

poolPreparedStatements: true

maxPoolPreparedStatementPerConnectionSize: 20

# 配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙

filters: stat,wall,slf4j

# 通过connectProperties属性来打开mergeSql功能；慢SQL记录

connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000

# 合并多个DruidDataSource的监控数据

#useGlobalDataSourceStat: true

jpa:

show-sql: true

properties:

hibernate:

hbm2ddl:

auto: create

mybatis:

mapper-locations: classpath:mapper/*.xml

6.对druid进行配置

package com.cnooc.config;

import java.sql.SQLException;

import javax.sql.DataSource;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.boot.context.properties.ConfigurationProperties;

import org.springframework.boot.web.servlet.FilterRegistrationBean;

import org.springframework.boot.web.servlet.ServletRegistrationBean;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.context.annotation.Primary;

import com.alibaba.druid.pool.DruidDataSource;

import com.alibaba.druid.support.http.StatViewServlet;

import com.alibaba.druid.support.http.WebStatFilter;

@Configuration

public class DruidConfiguration {

private static final Logger logger = LoggerFactory.getLogger(DruidConfiguration.class);

private static final String DB_PREFIX = "spring.datasource";

@Bean

public ServletRegistrationBean druidServlet() {

logger.info("init Druid Servlet Configuration ");

ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");

// IP白名单

servletRegistrationBean.addInitParameter("allow", "192.168.2.25,127.0.0.1");

// IP黑名单(共同存在时，deny优先于allow)

servletRegistrationBean.addInitParameter("deny", "192.168.1.100");

//控制台管理用户

servletRegistrationBean.addInitParameter("loginUsername", "admin");

servletRegistrationBean.addInitParameter("loginPassword", "admin");

//是否能够重置数据禁用HTML页面上的“Reset All”功能

servletRegistrationBean.addInitParameter("resetEnable", "false");

return servletRegistrationBean;

}

@Bean

public FilterRegistrationBean filterRegistrationBean() {

FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new WebStatFilter());

filterRegistrationBean.addUrlPatterns("/*");

filterRegistrationBean.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");

return filterRegistrationBean;

}

//解决 spring.datasource.filters=stat,wall,log4j 无法正常注册进去

@ConfigurationProperties(prefix = DB_PREFIX)

class IDataSourceProperties {

private String url;

private String username;

private String password;

private String driverClassName;

private int initialSize;

private int minIdle;

private int maxActive;

private String validationQuery;

private boolean testWhileIdle;

private boolean testOnBorrow;

private boolean testOnReturn;

private boolean poolPreparedStatements;

private int maxPoolPreparedStatementPerConnectionSize;

private String filters;

private String connectionProperties;

@Bean //声明其为Bean实例

@Primary //在同样的DataSource中，首先使用被标注的DataSource

public DataSource dataSource() {

DruidDataSource datasource = new DruidDataSource();

datasource.setUrl(url);

datasource.setUsername(username);

datasource.setPassword(password);

datasource.setDriverClassName(driverClassName);

//configuration

datasource.setInitialSize(initialSize);

datasource.setMinIdle(minIdle);

datasource.setMinEvictableIdleTimeMillis(minEvictableIdleTimeMillis);

datasource.setValidationQuery(validationQuery);

datasource.setTestWhileIdle(testWhileIdle);

datasource.setTestOnBorrow(testOnBorrow);

datasource.setTestOnReturn(testOnReturn);

datasource.setPoolPreparedStatements(poolPreparedStatements);

datasource.setMaxPoolPreparedStatementPerConnectionSize(maxPoolPreparedStatementPerConnectionSize);

try {

datasource.setFilters(filters);

} catch (SQLException e) {

System.err.println("druid configuration initialization filter: " + e);

}

datasource.setConnectionProperties(connectionProperties);

return datasource;

}

public String getUrl() {

return url;

}

public void setUrl(String url) {

this.url = url;

}

public String getUsername() {

return username;

}

}

public String getDriverClassName() {

return driverClassName;

}

this.driverClassName = driverClassName;

}

public int getInitialSize() {

return initialSize;

}

public void setInitialSize(int initialSize) {

this.initialSize = initialSize;

}

public int getMinIdle() {

return minIdle;

}

public void setMinIdle(int minIdle) {

this.minIdle = minIdle;

}

public int getMaxActive() {

return maxActive;

}

public void setMaxActive(int maxActive) {

this.maxActive = maxActive;

}

public int getMaxWait() {

return maxWait;

}

public void setMaxWait(int maxWait) {

this.maxWait = maxWait;

}

public int getTimeBetweenEvictionRunsMillis() {

return timeBetweenEvictionRunsMillis;

}

public void setTimeBetweenEvictionRunsMillis(int timeBetweenEvictionRunsMillis) {

this.timeBetweenEvictionRunsMillis = timeBetweenEvictionRunsMillis;

}

public int getMinEvictableIdleTimeMillis() {

return minEvictableIdleTimeMillis;

}

public void setMinEvictableIdleTimeMillis(int minEvictableIdleTimeMillis) {

this.minEvictableIdleTimeMillis = minEvictableIdleTimeMillis;

}

public String getValidationQuery() {

return validationQuery;

}

public void setValidationQuery(String validationQuery) {

this.validationQuery = validationQuery;

}

public boolean isTestWhileIdle() {

return testWhileIdle;

}

public void setTestWhileIdle(boolean testWhileIdle) {

this.testWhileIdle = testWhileIdle;

}

public boolean isTestOnBorrow() {

return testOnBorrow;

}

public void setTestOnBorrow(boolean testOnBorrow) {

this.testOnBorrow = testOnBorrow;

}

public boolean isTestOnReturn() {

return testOnReturn;

}

public void setTestOnReturn(boolean testOnReturn) {

this.testOnReturn = testOnReturn;

}

public boolean isPoolPreparedStatements() {

return poolPreparedStatements;

}

public void setPoolPreparedStatements(boolean poolPreparedStatements) {

this.poolPreparedStatements = poolPreparedStatements;

}

public int getMaxPoolPreparedStatementPerConnectionSize() {

this.filters = filters;

}

public String getConnectionProperties() {

return connectionProperties;

}

public void setConnectionProperties(String connectionProperties) {

this.connectionProperties = connectionProperties;

}

7.单元测试

package com.cnooc.dao;

import com.cnooc.pojo.TFile;

import org.junit.Assert;

import org.junit. Test ;

import org.junit.runner. RunWith ;

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

import org.springframework.boot.test.context. SpringBootTest ;

import org.springframework.test.context.junit4.SpringRunner;

import static org.junit.Assert.*;

/**

* Created by Administrator on 2018/6/11.

@RunWith (SpringRunner. class )

@SpringBootTest

public class TFileMapperTest {

@Autowired

private TFileMapper tFileMapper ;

@Test

public void insert() throws Exception {

TFile tFile = new TFile();

tFile.setId( 7 );

tFile.setName( "ceshi" );

tFile.setType( "ppt" );

tFile.setHaxi( "1111" );

tFile.setAddress( "cccc" );

tFile.setCreateTime( "11111" );

int a = tFileMapper .insert(tFile);

Assert. assertEquals ( 1 ,a);

}

8.对了启动类上别忘了扫描接口类

package com.cnooc;

import org.mybatis.spring.annotation. MapperScan ;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure. SpringBootApplication ;

@SpringBootApplication

@MapperScan ( "com.cnooc.dao" )

public class WordimgApplication {

public static void main(String[] args) {

SpringApplication. run (WordimgApplication. class , args);

}
