1.pom配置
遇到的问题：
1.根pom依赖的jar，maven插件子模块共享。
2.如果不需要向私服发包，install、deploy，就不需要配置distributionManagement
根pom.xml:

数据源配置
遇到的问题：
[email protected]注入不进来，原因：application.properties未找到，需要直接挂在classpath下。也可以通过@PropertySource(value={"classpath:application.properties"})指定路径
DataSourceConfig.java
package com.shfb.easyoa.report.config.datasource;
import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.jdbc.DataSourceBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import javax.sql.DataSource;
/**
* 数据源配置
* Created by shenjp on 2019/1/13.
**/
@Configuration
public class DataSourceConfig {
@Value("${easyoa.report.datasource.username}")
private String username;
@Value("${easyoa.report.datasource.password}")
private String password;
@ConfigurationProperties(prefix = "easyoa.report.datasource")
@Bean(name = "dataSource")
public DataSource dataSource() {
return DataSourceBuilder.create()
.username(this.username)
.password(this.password)
.build();
}
@Bean(name = "sqlSessionFactory")
public SqlSessionFactory sqlSessionFactory(@Qualifier("dataSource") final DataSource dataSource)
throws Exception {
final SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
bean.setDataSource(dataSource);
return bean.getObject();
}
}
application.properties
server.port=8080 server.servlet.context-path=/easyoa/report mybatis.type-aliases-package=com.shfb.easy.report mybatis.mapper-locations=classpath:mapper/*.xml easyoa.report.datasource.type=com.alibaba.druid.pool.DruidDataSource easyoa.report.datasource.driver-class-name=com.mysql.jdbc.Driver easyoa.report.datasource.jdbc-url=*** easyoa.report.datasource.username=*** easyoa.report.datasource.password=*** easyoa.report.datasource.max-active=10 easyoa.report.datasource.min-idle=0 easyoa.report.datasource.maxWait=60000 easyoa.report.datasource.timeBetweenEvictionRunsMillis=60000 easyoa.report.datasource.minEvictableIdleTimeMillis=300000 easyoa.report.datasource.validationQuery=SELECT ‘x‘ easyoa.report.datasource.testWhileIdle=true easyoa.report.datasource.testOnBorrow=false easyoa.report.datasource.testOnReturn=false easyoa.report.datasource.filters=stat,log4j
多环境部署
本地开发：在application.properties中增加配置：spring.profiles.active=dev
部署：java -jar xxx.jar --spring.profiles.active=prod
springboot获取配置
遇到的问题：
1.static 变量在启动时注入不进来，解决：
@Configuration public class PcacIntegrationUtil { private static String publicCertFilePath; @Value("${pcacmgr.publicCertFilePath}") public void setPublicCertFilePath(String publicCertFilePath) { PcacIntegrationUtil.publicCertFilePath = publicCertFilePath; } }
1.利用@PropertySource获取resource下面的资源，Environment获取属性
@Configuration
@EnableTransactionManagement
@PropertySource(value = {"classpath:DBsource.properties"})
public class DBBeanConfig {
@Autowired
private Environment env;
@Bean(destroyMethod = "close")
public DataSource dataSource(){
DruidDataSource dataSource = new DruidDataSource();
dataSource.setDriverClassName(env.getProperty("source.driverClassName").trim());
dataSource.setUrl(env.getProperty("source.url").trim());
dataSource.setUsername(env.getProperty("source.username").trim());
dataSource.setPassword(env.getProperty("source.password").trim());
return dataSource;
}
}
[email protected]获取resource下面的资源，@ConfigurationProperties找到该资源的头部@Value注入属性
@PropertySource({"classpath:redis-config.properties"})
@ConfigurationProperties(prefix="spring.redis")
public class RedisConfig {
@Value("${host}")
private String host;
@Value("${port}")
private int port;
}
[email protected]找到该资源的头部，通过getter、setter方法注入及获取配置
@PropertySource({"classpath:redis-config.properties"})
@ConfigurationProperties(prefix="spring.redis")
public class RedisConfig2 {
private String host;
private int port;
public String getHost() {
return host;
}
public void setHost(String host) {
this.host = host;
}
public int getPort() {
return port;
}
public void setPort(int port) {
this.port = port;
}
}
4.若是获取application.yml、application.properties中的属性，可以直接注入
@Value("${spring.redis.host}")
5.利用PropertiesLoaderUtil加载配置文件
public class RedisConfig3 { public static String host; public static int port; private static String property="redis-config.properties"; private static RedisConfig3 mConfig; static { mConfig=loadConfig(); } public static RedisConfig3 loadConfig(){ if (mConfig==null){ mConfig=new RedisConfig3(); Properties properties = null; try { properties = PropertiesLoaderUtils.loadAllProperties(property); host=properties.getProperty("spring.redis.host"); port=Integer.valueOf(properties.getProperty("spring.redis.port")); System.out.println(host+":"+port); } catch (IOException e) { e.printStackTrace(); } } return mConfig; } public RedisConfig3 getInstance(){ return mConfig; } }
