與普通springboot項目的區別:

/**
 * 配置程序入口，用於打war包
 */
public class SpringBootStartApplication extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(ShuJuApplication.class);
    }
}

favicon.ico配置：

    <link rel="icon" type="image/x-icon" href="${pageContext.request.contextPath}/favicon.ico">
    <link rel="shortcut icon" href="${pageContext.request.contextPath}/favicon.ico" type="image/x-icon" />

resources/banner.txt定義打印logo

簡單配置文件:

# 端口號
#server.port=8081
# 關閉默認favicon.ico
spring.mvc.favicon.enabled=false

# sqlServer 連接配置
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.datasource.jdbcUrl=
spring.datasource.username=
spring.datasource.password=

# sqlServer2 連接配置
spring.datasource2.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.datasource2.jdbcUrl=
spring.datasource2.username=
spring.datasource2.password=

# oracle2 連接配置
spring.oracle2.driver-class-name=oracle.jdbc.OracleDriver
spring.oracle2.jdbcUrl=
spring.oracle2.username=
spring.oracle2.password=

# oracle 連接配置
spring.oracle.driver-class-name=oracle.jdbc.OracleDriver
spring.oracle.jdbcUrl=
spring.oracle.username=
spring.oracle.password=

# 前段文件前綴，后綴  如 return "index";  會進入 /WEB-INF/view/index.jsp
spring.mvc.view.prefix=/WEB-INF/view/
spring.mvc.view.suffix=.jsp

# druid 連接池相關配置
spring.datasource.druid.initial-size=5
spring.datasource.druid.min-idle=5
spring.datasource.druid.maxActive=20
spring.datasource.druid.maxWait=60000
spring.datasource.druid.timeBetweenEvictionRunsMillis=60000
spring.datasource.druid.minEvictableIdleTimeMillis=300000
spring.datasource.druid.validationQuery=SELECT 'x'

spring.datasource.druid.testOnReturn=false
spring.datasource.druid.poolPreparedStatements=true
spring.datasource.druid.maxPoolPreparedStatementPerConnectionSize=20

# 日志輸出
logging.level.xx.dao=debug

多數據源配置:

DataSourceConfig:

/**
 * 多數據源DataSource定義
 */
@Configuration
@PropertySource("file:${user.dir}/src/main/resources/db.properties")
//@PropertySource("file:${user.dir}/db/db.properties") //生產環境配置文件外放
public class DataSourceConfig {
    /**
     * sqlServer數據源
     * @return
     */
    @Primary //主要
    @Bean(name = "sqldata")
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource sqlServerDataSource(){
        return DataSourceBuilder.create().build();
    }
    /**
     * oracle數據源
     * @return
     */
    @Bean(name = "oracledata")
    @ConfigurationProperties(prefix = "spring.oracle")
    public DataSource oracleDataSource(){
        return DataSourceBuilder.create().build();
    }
}

SqlServerDbConfig:

/**
 * 使用sql數據源配置
 */
@Configuration
@MapperScan(basePackages = {"xxx.dao"},sqlSessionFactoryRef ="sqlSqlSessionFactory" ) // 使用sqlServer數據源的包掃描
public class SqlServerDbConfig {
    // 引入 DataSourceConfig類下定義的DataSource
    @Autowired
    @Qualifier("sqldata")
    private DataSource sqldata;

    @Bean
    @Primary
    public SqlSessionFactory sqlSqlSessionFactory() throws Exception{
        SqlSessionFactoryBean factoryBean = new SqlSessionFactoryBean();
        factoryBean.setDataSource(sqldata);
        return factoryBean.getObject();
    }
    @Bean
    @Primary
    public SqlSessionTemplate sqlSqlSessionTemplate() throws Exception{
        return new SqlSessionTemplate(sqlSqlSessionFactory());
    }
}

OracleServerDbConfig：

/**
 * 使用oracle數據源配置
 */
@Configuration
@MapperScan(basePackages = {"xxx.ordao"},sqlSessionFactoryRef ="oracleSqlSessionFactory" )
public class OracleServerDbConfig {
    // 引入 DataSourceConfig類下定義的DataSource
    @Autowired
    @Qualifier("oracledata")
    private DataSource oracledata;

    @Bean
    @Primary
    public SqlSessionFactory oracleSqlSessionFactory() throws Exception{
        SqlSessionFactoryBean factoryBean = new SqlSessionFactoryBean();
        factoryBean.setDataSource(oracledata);
        return factoryBean.getObject();
    }
    @Bean
    @Primary
    public SqlSessionTemplate oracleSqlSessionTemplate() throws Exception{
        return new SqlSessionTemplate(oracleSqlSessionFactory());
    }
}

war包請使用build/buildArtifacts打包，避免tomcat版本問題，使用tomcat8版本
