如何在spring boot 1.3.x for embedded tomcat中添加tomcat会话复制

<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-session</artifactId>
</dependency>

# 启用会话复制
server.session.persistent=true
# 设置会话复制的存储方式
server.session.store-type=jdbc
# 设置会话复制的JDBC数据源
spring.datasource.url=jdbc:mysql://localhost:3306/session_db
spring.datasource.username=username
spring.datasource.password=password
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

                context.setManager(new org.apache.catalina.session.PersistentManager());
            }
        };

        // 添加HTTP连接器，用于会话复制
        tomcat.addAdditionalTomcatConnectors(createHttpConnector());
