与普通springboot项目的区别:

/**
 * 配置程序入口，用于打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定义打印logo

简单配置文件:

# 端口号
#server.port=8081
# 关闭默认favicon.ico
spring.mvc.favicon.enabled=false

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

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

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

# 前段文件前缀，后缀  如 return "index";  会进入 /WEB-INF/view/index.jsp
spring.mvc.view.prefix=/WEB-INF/view/
spring.mvc.view.suffix=.jsp

# druid 连接池相关配置
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.testWhileIdle=true
spring.datasource.druid.testOnBorrow=false
spring.datasource.druid.testOnReturn=false
spring.datasource.druid.poolPreparedStatements=true
spring.datasource.druid.maxPoolPreparedStatementPerConnectionSize=20

# 日志输出
logging.level.xx.dao=debug

多数据源配置:

DataSourceConfig:

/**
 * 多数据源DataSource定义
 */
@Configuration
@PropertySource("file:${user.dir}/src/main/resources/db.properties")
//@PropertySource("file:${user.dir}/db/db.properties") //生产环境配置文件外放
public class DataSourceConfig {
    /**
     * sqlServer数据源
     * @return
     */
    @Primary //主要
    @Bean(name = "sqldata")
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource sqlServerDataSource(){
        return DataSourceBuilder.create().build();
    }
    /**
     * oracle数据源
     * @return
     */
    @Bean(name = "oracledata")
    @ConfigurationProperties(prefix = "spring.oracle")
    public DataSource oracleDataSource(){
        return DataSourceBuilder.create().build();
    }
}

SqlServerDbConfig:

/**
 * 使用sql数据源配置
 */
@Configuration
@MapperScan(basePackages = {"xxx.dao"},sqlSessionFactoryRef ="sqlSqlSessionFactory" ) // 使用sqlServer数据源的包扫描
public class SqlServerDbConfig {
    // 引入 DataSourceConfig类下定义的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数据源配置
 */
@Configuration
@MapperScan(basePackages = {"xxx.ordao"},sqlSessionFactoryRef ="oracleSqlSessionFactory" )
public class OracleServerDbConfig {
    // 引入 DataSourceConfig类下定义的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包请使用build/buildArtifacts打包，避免tomcat版本问题，使用tomcat8版本
