50 | /** | |
51 | * Default configurer for Cloudhoppder that is automatically applied every time | |
52 | * a {@link MessagingBuilder} instance is created through | |
53 | * {@link MessagingBuilder#standard()}. | |
54 | * | |
55 | * <p> | |
56 | * The configurer has a priority of 40000 in order to be applied after | |
57 | * templating configurers. | |
58 | * </p> | |
59 | * | |
60 | * This configurer is applied only if {@code com.cloudhopper.smpp.SmppClient} is | |
61 | * present in the classpath. If not present, Cloudhopper implementation is not | |
62 | * registered at all. | |
63 | * | |
64 | * <p> | |
65 | * This configurer inherits environment configuration (see | |
66 | * {@link BuildContext}). | |
67 | * </p> | |
68 | * | |
69 | * <p> | |
70 | * This configurer applies the following configuration: | |
71 | * <ul> | |
72 | * <li>Configures SMPP protocol: | |
73 | * <ul> | |
74 | * <li>It uses one of "ogham.sms.cloudhopper.host" or "ogham.sms.smpp.host" | |
75 | * property if defined for SMPP server host address (IP or hostname)</li> | |
76 | * <li>It uses one of "ogham.sms.cloudhopper.port" or "ogham.sms.smpp.port" | |
77 | * property if defined for SMPP server port. Default port is 25</li> | |
78 | * <li>It uses "ogham.sms.cloudhopper.interface-version" property if defined for | |
79 | * the version of the protocol. Default is "3.4"</li> | |
80 | * </ul> | |
81 | * </li> | |
82 | * <li>Configures authentication: | |
83 | * <ul> | |
84 | * <li>It uses one of "ogham.sms.cloudhopper.system-id" or | |
85 | * "ogham.sms.smpp.system-id" property if defined for to identify an ESME ( | |
86 | * External Short Message Entity) or an SMSC (Short Message Service Centre) at | |
87 | * bind time</li> | |
88 | * <li>It uses one of "ogham.sms.cloudhopper.password" or | |
89 | * "ogham.sms.smpp.password" property if defined for an optional password</li> | |
90 | * </ul> | |
91 | * </li> | |
92 | * <li>Configures text message encoding: | |
93 | * <ul> | |
94 | * <li>It enables <a href="https://en.wikipedia.org/wiki/GSM_03.38">GSM | |
95 | * 03.38</a> encoding support. It automatically guess the supported encoding in | |
96 | * order to use the minimum octets for the text message: | |
97 | * <ul> | |
98 | * <li>It can encode using GSM 7-bit default alphabet if the message contains | |
99 | * only characters defined in the table. Message is packed so the message can | |
100 | * have a maximum length of 160 characters instead of 140.<br> | |
101 | * It uses one of "ogham.sms.cloudhopper.encoder.gsm7bit-packed.priority" or | |
102 | * "ogham.sms.encoder.gsm7bit-packed.priority" to set priority of GSM 7-bit | |
103 | * encoding.<br> | |
104 | * Default priority is set to 0 (disabled by default because most of providers | |
105 | * don't support it).</li> | |
106 | * <li>It encodes using GSM 8-bit data encoding if the message contains only | |
107 | * characters that can be encoded on one octet.<br> | |
108 | * It uses one of "ogham.sms.cloudhopper.encoder.gsm8bit.priority" or | |
109 | * "ogham.sms.encoder.gsm8bit.priority" to set priority of GSM 8-bit | |
110 | * encoding.<br> | |
111 | * Default priority is set to 99000.</li> | |
112 | * <li>It encodes using UCS-2 encoding if the message contains special | |
113 | * characters (Unicode characters) that can't be encoded on one octet. Each | |
114 | * character is encoded on two octets.<br> | |
115 | * It uses one of "ogham.sms.cloudhopper.encoder.ucs2.priority" or | |
116 | * "ogham.sms.encoder.ucs2.priority" to set priority of GSM 8-bit encoding.<br> | |
117 | * Default priority is set to 98000.</li> | |
118 | * </ul> | |
119 | * </li> | |
120 | * <li>If for any reason the message can't be encoded with standard encoding or | |
121 | * auto-guess is disabled, the default behavior is used: | |
122 | * <ul> | |
123 | * <li>It uses "ogham.sms.cloudhopper.encoder.default-charset" property to | |
124 | * encode messages using "GSM" (8-bit) charset</li> | |
125 | * </ul> | |
126 | * </li> | |
127 | * </ul> | |
128 | * </li> | |
129 | * <li>Configures message splitting: | |
130 | * <ul> | |
131 | * <li>Uses {@link GsmMessageSplitter} to split messages according to encoding: | |
132 | * <ul> | |
133 | * <li>If message is encoded using GSM 7-bit alphabet (7 bits per character), | |
134 | * one message of 160 characters can fit in a single segment of 140 octets (160 | |
135 | * characters * 7 / 8). If the message is over 160 characters, the message is | |
136 | * split in 140 octet segments including a 6 octet header meaning that each | |
137 | * segment can transport 153 characters ((140 - 6) * 8 / 7) and a partial | |
138 | * character (remaining octet).</li> | |
139 | * <li>If message is encoded using GSM 8-bit alphabet (1 octet per character), | |
140 | * one message of 140 characters can fit in a single segment of 140 octets. If | |
141 | * the message is over 140 characters, the message is split in 140 octet | |
142 | * segments including a 6 octet header meaning that each segment can transport | |
143 | * 134 characters (140 - 6).</li> | |
144 | * <li>If message is encoded using UCS-2 alphabet (2 octets per character), one | |
145 | * message of 70 characters can fit in a single segment of 140 octets (70 | |
146 | * characters * 2). If the message is over 70 characters, the message is split | |
147 | * in 140 octet segments including a 6 octet header meaning that each segment | |
148 | * can transport 67 characters ((140 - 6) / 2).</li> | |
149 | * </ul> | |
150 | * </li> | |
151 | * </ul> | |
152 | * </li> | |
153 | * <li>Configures session management: | |
154 | * <ul> | |
155 | * <li>Timeouts through properties</li> | |
156 | * <li>The window management through properties</li> | |
157 | * <li>The connection retry handling through properties</li> | |
158 | * </ul> | |
159 | * </li> | |
160 | * </ul> | |
